I am absolutely no expert, but to me this sounds like a pure update problem. Whatever it was, something did not properly upgrade to 22.04. In your situation, I would either:
Start from scratch with a clean 22.04. If you have a separate partition for your home folder, this should be a piece of cake. This is the easy way out.
If you want to get to the bottom of this: compare your filesystem (certainly the apparmor profiles & configs) with a clean 22.04. List up your packages with
sudo apt list --installed, then install them on a clean 22.04 VM, then compare filesystems, excluding home using e.g.
I know the first one sounds like Microsoft Windows advice, but it depends of course on how critical your current situation is.
