I think I solved the problem...

What seems to be causing all these random, for no good reason crashing of X-Plane is not X-Plane or the Challenger. I was getting this in my Event Viewer log:

"The description for Event ID 0 from source nvlddmkm cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

\Device\Video3
Error occurred on GPUID: 100

The message resource is present but the message was not found in the message table"

This is a Nvidia issue and has been affecting people playing many other other games, all types of video cards, Win 10 and 11, and has been going on for many months.

One poster on Reddit suggested running Nvidia Control Panel in "Debug" mode. That's what I've been doing and have had ZERO crashes with the Challenger and my frame rates are UP in the mid 30's to mid 40's. I've had X-Plane running all day with no problems.

With "Debug" mode de-selected the X-Plane / Challenger crashes within the first 5 minutes.
