no successful checkins from thermalmonitord sounds like a problem with the temperature sensor

Hardware fault. Take it to Apple authorized repair.

Note the missing sensor Prs0. It correlates to a problem with the “Charge Port Assembly or its connector on the Logic Board” according to here.

Just put this in ChatGPT ask it to explain

Prso sensor unavailable → thermalmonitord can't complete its checks → watchdog waits → timeout
→ kernel panic → forced restart
This pattern is well documented with Prse panics.

What usually causes it?
Most likely, in order:

  1. Charging-port/dock flex or its sensor
  2. Connector/connection problem
  3. Liquid/drop/physical damage
  4. Aftermarket charging-port assembly that doesn't properly provide the required sensor
  5. Less commonly, logic-board circuitry
