This did not work for me. Tried again today and I froze up within a couple of hours. I did an SMC last week and made it like 24 hours between freezes, so good luck. So far the only thing that works is just one single external monitor

An update on this - it's potentially too early to tell, but I may have a (terrible) workaround. In googling this issue, I am seeing a correlation to dual monitors being a factor. I generally use 2 external 4k displays, which may make me more prone to issues since it's a lot of pixels to redraw. Granted, this worked 100% fine in early Mac OS versions - I literally never had a freeze up ever before Monterey. Anyway, today after 4 freezes and reboots in 4 hours, I've been working against a single external 4k monitor for about 3 hours now without a freeze-up. Also, if you do freeze up, after a few minutes that seem like an eternity, the computer will self reboot and let you crash report to Apple. I would suggest making those reports if you are impacted.
