Can you point to the error in the log. With a first check I did not see anything that would point to a problem, maybe except some:
Transition to shutdown state: Shutdown due to webhooks request
Dumping gcode input 0 blocks
Dumping 20 requests for client 4064206888
But this typically is a Level 8 thing: MCU 'mcu' shutdown: Command request / Shutdown due to webhooks request
