Lastly if needed
OOBE RESET WIN
Quit the Creative Cloud desktop app (100% you must do this)
C:\Users\<user folder>\AppData\Local\Adobe\OOBE
The AppData folder is hidden in Windows by default. See Show hidden files, folders, filename extensions | Windows for instructions to access it.

Restart the computer and launch the Creative Cloud desktop app again.
