Is this the Teams account? You've posted in the Teams area which isn't very well visited. You might get more help in a Windows area.
FWIW, I am running Windows 11 and also have Evernote v10.32.4 working just fine. This type of issue has been seen with Windows 10 as well.
The normal first step is to use a program such as Revo Uninstaller, available free, to completely uninstall the program and ensure that nothing remains.
Also, I should ask if you have a Free account or are paying a subscription? If you are on a Free account then this is likely to mean that Evernote thinks you have multiple devices connected. So visit you account settings and revoke access for all registered devices. You are limited to two devices used on an account. So remove everything and then try logging back in. https://www.evernote.com/Devices.action
Once you have reinstalled and, if necessary, revoked access to all the devices in your account, then try reinstalling and logging back in again.

If you can see the program menus at the top of the screen/windows then try File | Sign Out | Remove my Evernote data
Otherwise, the most likely solution will be a complete uninstall being sure that the Evernote data is deleted. Then reinstall, login and allow the program to rebuild your data from the cloud.
 

There has to be a default notebook. If you don't choose one then Evernote will make the choice for you. @gazumpedhas referred to changing the default. Once changed you can delete the notebook you wish to get rid of.

You've found the definitive answer for the present. There's been no announcement of any plan to change and I doubt that there are any plans.
As has often been said, we're all fellow users here so the most you'll get is conjecture.
Once you reach the limits for a month or the 100,000 maximum then you cannot add any more notes in that month or, if you've reached the maximum, until you clear out and make room for new stuff.

These are user to user forums so your unlikely to get an answer from Evernote staff.
You should raise this as a support ticket...

From your video you seem to be working with the old version of Evernote rather than the new v10 product.
Your username and password combination should download the data from the cloud automatically. You should not need to do any import or export.
However, the Yingxiang product is not something I can speak to. I'm not even sure that the the Chinese data and the US versions have any interaction.
You might find it helpful to tell us which service you are using.
Standard approaches...
1. Be sure that you have the correct username and password for your account (it is easy to create a new one by mistake)
2. Uninstall all the Evernote programs
3. Reinstall the correct programs for your account - I'm not sure what you need for the Chinese product compared to the US.
4. Login with your correct credentials. Your cloud data should resync with your device. This can take sometime depending upon how much data you have.

I'm not sure that once the thumbnail is set that it is easy to change. So the size of the image needs to be reduced before the note is first created then added to a new note.
I, at least, still find thumbnails never change. Always the first one chosen by the program.

Works just fine for me.
Open the note to be exported Click the three dot menu button in the top right of the note Select Export PDF Follow the prompts for the layout of the Export PDF menu and click Export Choose the filename and destination folder The result is an Export Complete box with the option to open the containing folder or just OK.

This is the subject of another thread. There's is a fault identified with the Gmail add-on. This is, I think, unrelated to your PDF issue.
Check that the PDF filenames have the PDF file suffix. There's was a period when they disappeared and that broke the automatic file opening process.

On Windows I have to hold Ctrl and tap on the Help menu to see the troubleshooting options. Ctrl+R for Reload and Ctr+Shift+R to Force Reload

Right click the PDF and the bottom options will be View as Attachment and All Pages. I think you are looking for All Pages. Once you've made the change the options change to allow return to Single Page view.

My apologies, I was responding on the basis that this was a web browser issue as described.  I can see the wider issue. I would raise a support ticket.  It looks like some form of software protection against running scripts which might 'damage' your PC etc. It might even be something built into Electron.
Until then I guess that the only option in v10 is to highlight the URL and copy and paste into a browser.. Definitely not the preferred solution but a work around until you can get the issue raised for attention.

A possibly helpful discussion on this in another thread.
 

The most common cause is that the user logs in with a different account on the two devices. So ensure you are using the same login on the iPad and Mac.
Evernote.com/contact is the place to get support.

Could you temporarily change your default anguage to English and then see if you get the same issue.  This feels like it may be an OS/Evernote conflict or possibly a conflict with another application.  Do you get the issue with other shortcuts or just Ctrl+Alt+T/L? Change language and reboot your PC.  See what happens then change language back to Dutch and reboot.
If this isn't happening with your device and keyboard working in English then that might highlight a language issue.
You might quit the Evernote legacy program if you have that running.  I've experienced problems having the same shortcut running in Legacy and v10.  If that works then change or disable the shortcut in Legacy.
You could also change the Evernote shortcut to something else, again as a temporary test and see what happens.  Try something really unusual such ALT+Shift+= which isn't likely to be used by any other application or the OS.
A reminder that you can change the Evernote shortcuts: Ctrl+/ then select the ... menu item that appears when you point at the shortcut and select Edit.

Sounds like a support ticket is the way to go. Many others are successfully accessing task in v10.18.3 - works here just fine.
I don't wish to suggest you haven't thought this through but the good old fashioned re-boot the PC could be a solution and if not, then uninstall and completely remove all data directories then reinstall and allow EN to rebuild your data is likely to be successful. (To ensure you clean out the old installation use a program like REVO Uninstaller or just be sure that the %AppData%\Evernote and %LocalAppData%\Programs\Evernote directories are deleted after the uninstall process is complete).

Thanks.  Actually had to disconnect my calendar and then reconnect.  I suspect it was a hangover from having been in the Calendar Beta trial.

This change has been present since the switch to version 10.  There is no setting in v10 to achieve this. I suspect that this will never return but I could be wrong
Your only option is to go back to the legacy version if this is key to your workflow.

The Web Clipper is a stand alone plug-in for a number of browsers. Once installed it creates an icon button on the browser toolbar.
I'm not sure what you are requesting about adding to shortcuts - could you describe it in a little more detail?

@John Burroughs The new version of Evernote is not configurable in terms of the location to store your data.  The good news is that we know your data is intact since you can view it via the web.
My recommendation would be to thoroughly uninstall Evernote then be sure to delete all left over data directories.
AppData\Roaming\Evernote is the directory which Evernote v10 uses. Still delete it.
I'm not sure where AppData\Local\Packages\Evernote.Evernote_q4d96b2w5wcc2\LocalCache\Roaming\Evernote has come from. Even so, delete it or if you prefer copy it to another location for safekeeping. It isn't serving a useful purpose and may confuse the reinstallation.
Once all vestiges of Evernote have been removed reinstall Evernote from the installation program. Once you log in you should find all your data is restored from the cloud and properly organised. The resync process can take a few minutes to process so give it plenty of time to grab everything from the Cloud before attempting to open a document.

THis is an issue with the Windows desktop application.  Depending upon how you added the PDF to the note, sometimes the filename is stripped of its file suffix. Eg: filename.pdf becomes filename
You've discovered that this is the case for you. Right click on the PDF and select Rename and add .pdf to the end of the name. That should fix the default program open issue.  I get this when adding PDFs from my scanner and also adding a PDF by sendto or dropping on the desktop shortcut.

@herdianto Did you ensure that you deleted the program and data directories before reinstalling? That is usually also required in order remove any corrupted configuration and data files.
%AppData%\Evernote
%LocalAppData%\Programs\Evernote

This already exists in part... If you open the note without the snippet/card column then the note title appears at the top of the screen when you are scrolling. But not if the snippet column is showing.

Similarly if you open the note in its own window then you get the same result. Could that be a workaround until the suggestion you make can be implemented?

An alternative and quite straight forward and useful if the program you want to startup isn't listed by following the process that @Mike P points to. A standard Windows function.
Win+R shell:startup Create shortcut to %localappdata%\Programs\Evernote\Evernote.exe  

@PNG Coops If you are editing a document attached to a note but outside Evernote I find that you need this process to save the changes back into the note attachment.
1. Open the attachment
2. Make the changes
3. Click the save button or type Ctrl+S
4. Close the attachment
If you, instead, just close the attachment then any changes appear to be saved to a copy in one of the temporary directories rather than in the Evernote attached version.
THis is my experience YMMV
