I had a similar situation. Turned out to be a grounding issue.

Kept randomly losing the root m.2 drive and when I’d plug in monitor/keyboard I could type in the terminal, but most executables would not work.

Hard reboot and it’d be good for a few weeks or few months. Then it’d die again. Really annoying losing it because my calendar and email gui is on it.

Once I noticed a small static shock when I touched the case.

I taped a wire to the aluminum case and taped the other end to a grounded chassis of another computer and all was good since then
