Same here, loading the sim okay, then in world map, choose inibuilds A300, choose airport etc, then click fly, then CTD!?? Twice in 2 days!. error details gives this path
.....\AppData\Roaming\Microsoft Flight Simulator\packages\inibuilds-aircraft-a300-600\m44477453e77732a1_0.dll
Never had this with any other aircraft, including the microsoft A310, which by the way is freeware and works better out of the box for same systems etc..
