So, by reading the link and also the above posts, i understand that there is no real answer to this issue, or that all solutions have not yet been identified …
But, i was able to fly without issue after having just reset the Nvidia 3D settings to default…
Now it seems ok to fly, no more error, and it was a flight on screen, not with the Quest2 in VR.
Also my community is empty, so no adds-on active…
