I'm on BigSur 11.4 with the same issue as describe: plug-in USB-C Dell monitor results mostly in system crashes, 1m - 2h later during web conferences / work. Same crash reports as posted here many times.

Updating to Monterey BETA 2 fixed the issue for me as well :)
Can somebody explain how to get this beta?
