I was running version 3.4.2, three weeks ago the app started having a problem. The app loads but as soon as I click on anything, like File in the menu bar, the app freezes with the message (Not Responding) in the title bar and the app's window is grayed out. At this point the app is not responsive. Stopping and restarting the app results in the same behavior. I tried to uninstall the app and reinstall it, but no joy.
The app version is 3.4.2
Windows 10 version 1909.
Hardware is all high end, so no problem there, and the app was working.
I think the 3.4.2 version broke something or a windows update broke something.
