Creative Cloud is initializing - stuck in installer

Hey guys,
I just got a new PC that runs Windows 11, not Windows 10 anymore. Now I'm having a problem where when I install Creative Cloud, I always get this message: "Creative Cloud is initializing." It goes on to say, "To resolve this issue, Creative Cloud is required, but it is missing or corrupted. Download and install a new copy of Creative Cloud."

I've tried all sorts of things, but nothing helps, and I'm hoping someone can suggest another solution.

I've tried:
Restarting the PC, uninstalling and reinstalling, including using CC Uninstaller and the Adobe Creative Cloud Cleaner tool, turning off the firewall, turning off my antivirus program, and running this command list via the CMD console in Windows, as described on the help page.

I'm at a loss, maybe someone can help me. Regards, Kraken
