Bush Trips not starting after latest update

Installed all the latest updateslast night. All drivers up to date and latest Windows version.

Trying to continue my bush trips encountering problem now. I can choose a particular bish trip and start a particular leg of it. Then the SIM gets stuck, endless screen, never get to the phase where I see the plane on the runway. Just stuck. GPU and CPU busy….

Does anybody have a clue what the problem can be?

Your input will be appreciated.
