You don't describe the problems with anywhere near enough detail to guess at what the underlying issue might be.
https://wiki.archlinux.org/title/AMDGPU << Has a troubleshooting section that might help.
That's because this is the HN comment section, not the f.d.o bug tracker.
Since you seem to care, what I'm seeing is likely #2220, though the real problem for me is that dmesg output is not particularly helpful on its own and it's the entire desktop that crashes (as opposed to a single application that you could set Mesa/amdgpu debug flags on.) The fact that it "only" crashes about once per week complicates things further; aimlessly enabling debug options would probably result in getting buried in logs.
