System completely freezes CPU Stuck / Hardware Error

Hello. So recently I got the issue of regular freezes on my ryzen 5 computer, especially when suspending to ram. But I also already experienced this issue turning the computer off.

I don't know when the issue occured, as what hardware change might have been responsible for it.
I have already tried resetting the cmos to no avail.

This is what such a freeze looks like:

• computer completely freezes when suspending computer to ram (systemctl suspend)

• gets completely unresponsive

• after a while computer softreboots

upon reboot related error message appears and the pc proceeds to boot normally:

Any idea what this might be?
Is there some driver I am missing here or might this be a hardware related defect?
best regards

tl;dr this is roughly the message I'm getting after reboot [Hardware Error]: CPU 5: Machine Check: 0 Bank 5: bea0000000
