Have tried several things, so many that I do not recall which one did resolve the Crashes to Desktop. I went trough this:[Walkthrough] Avoiding CTD´s - Community Troubleshooting Guide and have also downloaded Fortect and run it. This did not solve the problem. I think changing in Windows 10 the flight Simulator Cash file and memory and updating some airports in the Content Manager. The event Manager did not help as I do not understand it well enough. Then W11 also started working (edited)
