Hi @shkit,
i have found the same occuring on my system. Then i googled a bit about this error and found another electron-based-app with the same error:
kit - Fresh install has high idle CPU on Windows 11
In this error report, one user renamed the .exe file of the programm by adding a 2 to it to fix this. I tried the the same with a fresh evernote 10.94.2 install on my pc, renamed the Evernote.exe, corrected the link and it´s icon in the start-menu and it seems to have stopped the problem:
C:\Users\<username>\AppData\Local\Programs\Evernote\Evernote.exe -> Evernote2.exe
This don´t make sense to me, but now the high cpu-usage in the background has stopped for at least for now.
Starting Evernote automatically with Windows boot did not work until i corrected the evernote entry in the registry under Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
At least this could be a weird workaround for those who need offline access to evernote and don´t have access to the ms store version.
Btw:
All these changes can be made using a powershell-script containing 3 commands and the adapted start-menu-entry as a source.
I use the portable binary of evernote-backup, works fine on windows 10 and 11.
Then i start it once every week with the windows task scheduler. I just have the scheduler start an easy .bat-file, which starts the backup-process.
