It looks like your drive is going offline randomly, or at least, when it warms up a little. All the IO errors look like various subsystems trying to write to something that’s not there anymore, which is why there’s nothing visible in the logs when you look later.
Could be the drive, could be the drive controller on the motherboard, could be just that your nvme drive just needs to be taken out of its slot and reseated, could be something weird in your BIOS setup that’s causing mayhem (bus timings, etc).
Personally I’d reseat your drive in its slot first and go from there.
