Whelp, I guess I should've stuck with the OT approach of my Home Assistant: "Don't touch it if it works!"

Did updates today, as I only was 11 months behind. But now it keeps crashing after a few minutes. Does give Raspberry Pi undervolt warnings though (but it has done so for years.)

Is this the sign that my temporary trial setup on an old Raspberry Pi 3 I had laying around is due for some better hardware?
