Hi all, found this thread by googling the first line of my crash report. I am getting the exact same issue (16", 11.4) only I am using the Pluggable TBT3-UDZ TB3 dock. The issue seemed to be related often to one of my external monitors turning on/off or the cables being plugged in or out. I'd get the fan whir and a crash out to restart. It sometime happened when the dock itself was plugged in or out (which would of course include the monitors disconnecting). The only time it happened when I left the dock connected was when the monitors were doing something. Switching to the HDMI ports on the dock from DP (this dock offers the choice of DP or HDMI for both of it's outputs thankfully) seems to have fixed the issue. My guess is that it is related to the signal that Display port sends back to the computer (called EDID?) to tell it whether the monitor is switched on or not. On DP, if I turned a monitor off it would blank out the other displays for a moment and rejig the arrangement in settings. With HDMI, turning the monitor off doesn't do this and the monitor is still listed in settings. Hopefully that helps someone else out until apple pull their socks up! Richard.

Just an additional point on the graph. I have the issue (with my pluggable TB3 dock) far, far less now my monitors are on HDMI vs DP. Although I did get it once every so ofter, mainly after waking my machine up. However, since unplugging a powered USB hub that I had plugged into the TB3 dock (by powered, I mean it has it's own power adapter) I have had zero issues. All the same peripherals are plugged in via an alternative dock (both are just regular USB 3.0 docks, nothing fancy) and all is well. So far 🤞🏻
