Game Crashes After Turning off AutoPilot

This has happened to me a few times recently. Mostly on longer flights. When it happened today I was flying from Keflavik to Brussels in a Diamond DA62. This was hour 3 of the flight, as I had the sim rate up for most the flight, though when it happened my sim rate was normal. I was descending and I decided to fly it manually so, I press Z to take the autopilot off and the game crashes.

When it crashes, it makes my screen go black and my monitors go into power save mode so I can’t tell if it crashes to the desktop or what. I know my PC is still running as I can hear the fans, but the only way to get my PC functioning again is to power off and power on.
