At startup X-plane 11 give a black screen for few seconds, then the desktop appear, then new black screen, then X-plane 11 stop working. Attached log.txt. Before this issue an Windows 10 update has been installed. I already tried to roll back to all available previous configurations, but this did not solve the issue. The same situation also occurs with the installer, then it is impossible for me to reinstall X-Plane 11. Thanks for your help.
