Unable to expand side navigation

[PMB19 0]

I am unable to expand the left-side navigation in Windows.  Pressing F10, or View -> Left Panel does not change the side navigation at all.

 

What can I do to resolve this?

 

My specs:

Windows 10

Evernote 6.21.2.8716 (308716) Public (CE Build ce-62.5.9981)

Happy to provide activity logs to support team, just didn't want to post them publicly.

Hi, and welcome to the forums. Often the simplest thing for such a problem is to exit the program completely (File > Exit; or end all Evernote processes in Task Manager; the red X box at the top right of the Window only closes the interface, not the program as a whole), and then restart it. This can clear out gunk that's gotten stuck in the computer's memory. A reboot has the same effect
