Same issue for me similar log txt as the ones posted above - currently unable to fly the aircraft.
I was trying to learn it and was sitting at the gate until I broke something (Lol amateur move) and so I re-started the sim anyways because performance was poor could also have been the weather due to heavy fog at my lcl airport..
Once I've restarted the sim and selected the plane I already noticed longer loading times and then the screen came up asking me to either continue my last flight or start the new one once I answered "no" the sim crashed. I then tried answering "Yes", Sim crashed aswell, I deleted the preference folder - no luck, I re-installed the aircraft - no luck either. I then tought of selecting the plane with Engines already set to on, also no luck there, if anyone got an idea or a work around let us know! :-)
Kindest Regards and good luck to the devs. Still a very beautiful plane by the way!
