I am crashing immediately.  If I go in Free Fight and enter as an example KSAN  to KMIA.  Edit Fuel, real world weather hit fly.  Loads.  Sim loads to runway and in 5 seconds or less <crash> Microsoft Flight Simulator has stopped working.  A problem caused the program to stop working correctly.

please help - very frustrating.  Starting in Free Flight with a simple flight shouldn't be crashing in the new 1.0 release.  In fact, never had this issue in the previous 0.X releases.
