Three times I've had X-plane crash while loading the DA40, and then I finally managed to get it loaded by loading another plane and then switching to the DA40, and then X-plane crashed when I started the engine!
It seems to fail due to an invalid VRconfig file, which is odd given that I'm not using VR.

I'm on Manjaro Linux with a 5.17 kernel using an AMD GPU with the latest drivers.
