Just a quick post as I encountered an error with Adobe Creative Cloud not being able to update, on MacOS Monterey.
The update stalled at 1% and then throws Error 1001. I rebooted a number of times and didn't fix the issue. After searching on these forums I found some dated info of people saying they have to uninstall/reinstall CC with some not being able to uninstall.
I was able to solve the problem by running the CC Uninstaller in /Applications/Adobe Creative Cloud and choosing repair. The first time running the repair showed some errors, just click through them and wait for the repair to finish automatically. Once it has finished, run it again and choose repair again, it will then run with no errors, and once it has completed you can open CC and it will update with no problems.
