The game does need some patching and AMD also has some work as they are not strong in DX11's.
As for crashing I haven't seen any on my system but I think it come down to resources. i've seen the game pushing system ram usage over 16GB's after a couple hours so if you don't have 32GB's that will be an issue. And i've also seen simliar behaviour with Vram I will start at 6.5GB then climb to 10GB after about 2 hours of play time.
The dev's are aware of the issues
UPDATE - 1/24/22 We have released a patch (v.1.0.3) to address the memory leak issues. Please refer to the Patch Notes here.

I also hope AMD is continuing to work on improving FSR its only really usable in Ultra quality mode the rest just take to much of a hit on image quality.
