I'm connecting my external screen using a USB C cable, and have a couple of disks attached to it via USB C.

The external screen / USB C may be the issue, I don't think it's the USB C dock.

My crash report looks pretty much like yours and I suspect it's the graphic adapter driver not coping with power saving (power nap, in this case) correctly, especially since all the crash reports I've seen seem to pin the blame on com.apple.iokit.IOGraphicsFamily.

I disabled power nap, (System Preferences->Energy Saver->Enable Power Nap while...) and it seems to work around the issue.

I try to re-enable it after each update - only to disable it again when I realize the issue was not resolved (10.15.5 was the latest attempt).

While power nap is not a very important feature for me, it's pretty much annoying that it can't be used with the top of the line brand new MacBook Pro 16", especially since this issue has been happening to so many people for so long.

Finally someone with the new MBP16 also having this issue. Everything was fine until I updated to the latest OS 10.15.4 2 weeks ago. Just can't get it to sleep all the time. 50% of the time, my MBP would restarted and showing the same error report. I tried to call Apple Support, they guided me to reset SMC but still having this issue.

I had this problem when I closed the lid to put computer to sleep, When I opened the lid up to start working again it Generated a report like that. To Fix, I unchecked the automatic graphics switching in system preferences, energy saver. The MacBook Pro 16 has the AMD Radeon Pro 5300 4 GB and Intel UHD Graphics 630 1536 MB. Switching between the two I think must cause it to time out or something?

I thought disabling "Automatic graphics switching" fixed the problem with me but it came back. The only time I had the problem was when I had the power cable plugged in closed the lid down to let it charge overnight. The next day it would give the report that the computer was restarted because of a problem. I just quit closing lid and charging at night in sleep mode. Haven't had it give me any more reports after that.

Switching powernap off seems to work.

48 hours without a crash.
