I had already uninstalled Creative Cloud but its zombie folder was still there. (Win11/64bit/most recent updates.) Looked for hours, tried tons, nothing would work. Maybe for you Adobe's unPinCCF tool would work, or using regedit to set System.IsPinnedToNameSpaceTree to 0 would - but not for me.
TLDR (thanks, Aubrey and Bortao) Delete the following registry key (after making a backup of your registry ofc):
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\0E270DAA-1BE6-48F2-AC49-5CE0DBECC398
Bortao reports- "The last part of the number is random, so open Regedit and browse to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace, find a key starting with 0E270DAA-1BE6-48F2-AC49 and remove it." Me, I found it by Ctrl-F and looking for "creative cloud files" until I landed on that one. Deleted it, rebooted, GONE.

This is NOT the only thing that worked for other people, so I should post my notes from this long trek, maybe one of the simpler paths might work for others
