My 2018 Macbook Pro (Monterey 12.6) keeps crashing/restarting. It seems to be related to sleeping or waking from sleep, and can also be triggered by plugging in or unplugging a 2nd monitor.

This is the crash log:

    Start in safe mode (hold shift while booting) and see if the problem persists.

I was also having crashes (although I didn't see this particular panic) and it seems to be related to clamshell mode. Since I've started leaving my laptop cracked open even when using the external monitor, the crashes have stopped.
