After updating to Windows 10 - 20H2, I get the following error when trying to run any Office365 desktop Apps:

" windows cannot access this specified device, path or file. You may not have the appropriate permissions to access the item"

Tried the usual uninstall/reinstall of office as well as check permissions. Tried removing the profile and recreating windows user profile. Same error.
