UPDATE: It crashed again today, and I was able to pull some logs and check the temperature at the time of the crash. (91 degrees which dropped to 71 degrees right before crashing?

I mean, I’m not saying that errors on the drive are the CAUSE of the problem, more likely a symptom, but it does look like it just straight up crashed, right?
