Creative Cloud repair message - and then repair and installer not working

Hi all, I purchased a secondhand Mac 27" late 2015 (OS updated to Big Sur 11.5,2) which came with the Adobe creative suite installed, as the previous owner was a designer. I currently don't need to use these apps and don't have a subscription for them. However I am regularly getting an error message stating:

"Adobe Creative Cloud

Adobe Creative Cloud, needed to resolve the problem, is missing or damaged. You can try to repair to fix the issue. If the problem persists, download and install the new copy from 'http://www.adobe.com/go/adobecreativecloudapp'."

If I click on repair, nothing happpens. I've also tried using the CC uninstaller and although I can download and run it, never get the promised "Creative Cloud desktop has been successfully uninstalled" message.

Any tips or tricks as to what's going on here, and how I can resolve by either updating the CC app or successfully uninstalling it?

TIA
