Odd behaviour when I reboot iMac

I have an iMac running the current macos (Big Sur, 11.1) with Creative Cloud installed. Every time I reboot my computer and restart Lightroom Classic, I get a pop-up that says "Adobe Creative Cloud is needed to resolve this problem. However, it is missing or damaged. Please download and install a new copy of the Creative Cloud from 'http://www.adobe.com/go/adobecreativecloudapp'." Mind you, it never says what "this" problem is. Furthermore, even without downloading anything, the apps end up openin gjust fine. Any idea what is going on?
