Installing Creative Cloud: error 81 and how to fix it on MacOs Big Sur

Question

I tried to reinstall Creative Cloud on my iMac Big Sur but it doesn’t work: error 81. I saw that I have to access the Activity Monitoring because there is another installation process for Creative Cloud, but I can’t find it. It seems that there is no active Adobe process on my Mac, but I can’t install the Creative Cloud package. Someone could help me? Thanks!

In addition to all other advice, the current Creative Cloud app doesn’t seem to support Big Sur (macOS 11) anymore:
