The first time I read your symptom, my first thought was "I bet he has an nVidia card, just like I did before switching. So, acknowledging that you never run X and might not even have any nVidia drivers installed (if you do, I suggest removing them, under the circumstances), is your built in card an nVidia? If so, do you have a less than 5 year old Radeon to temporarily install while disabling your nVidia in BIOS? After my horrendous intermittent hangs and reboots of November and December 2020, I would never use any nVidia graphics unit with Linux again. If I somehow acquired a computer with built in nVidia graphics, I'd disable the built-in and use a Radeon. Even if I didn't use X.
