On a Facebook forum I was told that the issue I was having was to do with using DirectX 12 (Beta) in the sim settings. I tried DirectX 11 and this time the sim didn’t crash so that might work for others, too?
Thanks for that. That doesn’t say much except pointing to the Flightsimulator.exe could be causing the error.
Try taking out the card and disconnecting the cable then replace and see if that fixes your issue. I had a problem similar to yours in another game and doing that fixed the problem.
