PR4100 trouble deleting apps

Lately, I have been trying to uninstall the Plex or GoodSync apps. First of all, the PR4100 takes forever just to load the apps - what’s up with that? Second, getting the app to uninstall prior to re-installing an updated version doesn’t happen, once I click on the uninstall button, PR4100 appears to freeze with the updating screen. I log in after 2 hours or 24 hours and the same app has not been uninstalled. What gives?
Firmware Version : 5.18.117 for the PR4100
Windows 10 Pro
Version 21H1
Installed on ‎2021-‎09-‎25
OS build 19043.1348
Experience Windows Feature Experience Pack 120.2212.3920.0
Thanks - any help would be appreciated. Why oh why did I upgrade to OS5? Everything was working fine before that!

@charvie Is your PR4100 Indexing or Generating Previews?
If Yes,

  • Turn Off Cloud Access from the Cloud Access tab
  • Reboot
  • uninstall the apps

No it is not indexing or generating previews.
There is no turn off Cloud access in the Cloud Access tab
Any other suggestions
