FW16 Boot Drive Missing - Any Fix?

I’ve actually been getting this error on and off for months without having swapped out my SSD at all. It only happens after my FW16 has been in Hibernation for a little while. No idea on timing because it’s always overnight. I wake up to that error and the fans kicked on at full tilt and a lot of heat coming from the bottom for some reason. Have yet to figure it out. Also running W11 on a 4TB 2280 SSD. I have a ticket to support on thermal issues referenced in this thread so hopefully I’ll get a new mainboard that will solve both issues, but I hope there’s a better solution.
