I believe I might have resolved this...
Interesting enough, while dabbling in mission building in a military simulation game called ArmA 3, I was consistently getting CTDs when I went live to test, due to a paging file error. So I blew away my pagefile.sys and generated a new one. That immediately resolved my problems in ArmA 3. And now with some flying around the PacNW this afternoon with PlanG v4.01 b262 always connected, I didn't receive a single CTD. I was certainly flying around areas with extensive 3rd party scenery, because I just bought FSimStudios' CYVR and CanadianFSimStudios' CYAZ and those were the airports I was departing and arriving at.
So it looks like both simulators CTDs were caused by a corrupted paging file. I can't remember the last time I hade a corrupted pagefile.sys - maybe as far back as Win2000. I'm not sure why the CTDs only happened in MSFS 2020 when PlanG was connected, but maybe in that set of circumstances MSFS or Win10 uses, or causes the paging file to be utilized.
