Please check if you are able to update the app as directed here - Update Creative Cloud apps?
If it still doesn't work, then you might have to uninstall and reinstall the Creative Cloud Desktop app itself - Uninstall the Adobe Creative Cloud desktop application.
Hope this works out, please let us know.
