Can you still SSH to the machine when it’s in that state? If you can it’s likely to be a problem in the graphics stack, if you can I’d probably start by running memtest86+ for a full cycle to rule out memory issues. After that, checking things like CPU temps would be good.
Assuming that’s all good, check for anyone else reporting issues with the same motherboard, CPU, GPU, or other components
Good luck, this sort of thing can be quite frustrating to get to the bottom of.
