Woo! Glad you got it backed up before abandoning ship. 
I'm not sure what happened but it sounds frustrating to say the least.
Maybe install POP!_OS the AMD version if you want to try that card again. Also consider Debian 11 you can choose what desktop-
environment(s) you want or create a minimal base system and install only the necessary packages & dependencies.
You said "never again with AMD cards in Ubuntu" but I hope later on you can get it to work on your test rig.

It was my personal PC and have all the photo,video memories of me and my family,my little daughter,video courses that I continuously learn in information technology,and a bunch of other important things to me.I have gone with Ubuntu 22.04 LTS and sticking back to it and never looking back now,I will never know what it was the cause but I also took the time to read your links to this problem,still no good and no solution to me,so locking the thread.
