Thanks a lot for bringing this to my attention, and sorry for the inconvenience (and my late reply). If I read this right, then this crash happens when you push the button to set the flight plan, is that correct?
Indeed, from the log it almost sounds as if you’re trying to set a flightplan without having a flightplan… but of course then the button should be disabled, and usually it is as far as I can tell.
If you could describe exactly what you do/did before the crash, that would help a lot.
