HELP! Updated my Mac to Catalina and now can't install any Adobe programs (Error Code: P81)

I updated my Mac to Catalina (version 10.15.2) and every time I try to install any Adobe app it keeps saying:

Sorry, installation failed

Another installer is currently running, which must be closed before installing this product. Please close or wait for other installers to complete. (Error Code: P81).

I have tried restarting multiple times and checked activity log but don't see any Adobe programs running. What do you suggest I do? Everything was working fine when I was on High Sierra (really regret updating now)

UPDATE: In the end I completely wiped / reset my Mac and tried again. This time they installed and work (Photoshop, Illustrator, InDesign, Acrobat e.g). Sucks that I had to do that but there was no other alternative.
