So yesterday I downloaded FlightGear. Please note I am running a top of the line 2020 MacBook Pro (Intel). Yesterday it wasn't launching, and then I just gave up on it. Today I relaunched it for the memes but it actually launched. When I downloaded an airplane, selected a location, and then pressed 'fly'. The app quits, and an Apple prompt saying 'fgfs quit unexpectedly'. I am running MacOS Big Sur (intel i5). I did once manage to get it to not show (the error), but no game launched.
Thanks,
Jaiveer Talwar
