I have this happening all the time when I am experimenting with different OpenXR settings vs Renderscale. I leave VR in the sim, open openXR dev, change the scale, go back into the sim, start VR again and that never works. Always the error message… Would be greatful if anyone could tell me if there is another way? This way it is very frustrating to test because I have to restart the sim every single time… (and as we all know, that might take a while…)
