Survivor bias is very strong. It is survival of the fittest. I have been PC gaming since the 90s having started on the original Doom, and I have never had so many issues with a game, or any program.
I have supported, helped and commiserated with so many who have never been able to get MSFS to work or it has just failed after working. It is almost beyond rational cause and effect.
You and the others who have no problems are lucky, and I wish that you continue to enjoy your success, but it should also be recognised that MSFS is problematic for many and inherently badly designed and supported for VR.
