Issue on booting - "SODC report detected: AP watchdog expired"

Not sure if I am in the right place, directed here by apple support staff. On starting my MacBook Pro M3 Max this morning it went into a cycle of rebooting after about 1-2 mins. I managed to see the following error message "SODC report detected: AP watchdog expired" before the screen went totally black and the fans went to full speed. Any thoughts on this? Sequoia 15.2, no external drives or hardware plugged in. Thanks
