Ever since Illustrator update 26.4 and 26.4.1, Illustrator drops access to my CC libraries and requests and install of Creative Cloud which is installed and up to date. I did uninstall CC and reinstall, no change.
All ok on other apps, just Illustrator and as it's an app used more often it's not user friendly. My only fix is to keep shutting down the program and restarting, please fix.
