Hi, I have exactly the same problem since the last update. My sim ran almost perfectly before, without any crashes and smoothly at 52 - 57 FPS. The crashes occur irregularly in every phase of a flight, but 80% of the time after landing, before any crash, it was a very stable and smoothy flight. I also tried the solutions you have already described, without success. If you have found a solution, please let me know….I am very frustrated
