Hi all,
I used to have some screen flickering issues that were supposedly motherboard or RAM related. At some point, I also experienced very frequent crashes and even a kernel panic once. I'd also notice a specific order of sequences, which looked something like this (though I can't remember exactly): after the crash the first boot wouldn't work properly and I'd have to restart, the second boot would get me to the login manager, but I sometimes wouldn't be able to log in, the 3rd boot would get me into a session that lasted only a little while before crashing, and finally the 4th boot would last me quite a while, sometimes even a day or two of running without issues, until the system would again crash and the cycle would restart. So I recently put together my PC on a new motherboard with a different pair of RAM sticks. I stopped having the flickering issues, but my system still shuts down unexpectedly sometimes. I noticed this happens especially often after just finishing a chess game on chess.com (which is new and wasn't problematic in the past), though I have no idea what that would have to do with anything. Then the first time I open Firefox again in a new session, I get these notifications, which might hint at the issue too:
1. Due to a technical issue, your default search engine has been changed back to Google. To change the default search engine, go to settings.
2. The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.
Here's my last journalctl -b boot log:

and here's my last dmesg log:
https://0x0.st/8kqS.txt
Noticing some amdgpu errors in there, but not sure if they're related or what they mean.
Could you please help me figure out the issue here?
