Do a complete uninstall using AppCleaner. TPAI users sometimes are successful when they remove a file from the Library called CoreLib or something like that. Check out the recent thread on how two do that. I think I have also heard that .plist files associated with Topaz can be a problem.
I have only just started using TGPAI again since purchasing my Mac mini M4. Prior to that I had an M1 16GB. So can’t compare.
Also note that no one from Topaz has contributed to this thread since it opened almost three weeks ago. You could do worse than open a support ticket.
