Crashing

Hi! since I updated my iMac on Big Sur Rush does not work anymore! It always crushes so i cannot work - unfortunately not even on my desktop but also on my iPad pro. I uninstalled the other Applications but it still does not work.

I have contacted the support, they had try to fix it; after that it worked one day! Apple support meant, it is an Adobe Problem, Adobe support meant, it is an Apple problem. So...what am i suppose to do?
