Hi there,
This bug has happened to me for the first time yesterday during a climb out of KPHL.
Not sure if this is helpful, but the only different thing I did compared to my other flights was to use the Simbrief import to get my route loaded. Normally I enter it manually. I also copy primary to secondary flight plan but was not trying to activate it.
Pressing a right RSK on one of the waypoints caused it to freeze up. I was trying to remove a speed restriction but it crashed as soon as I pressed the waypoint right RSK button. Again, I’ve done this many times before apart from loading the route from Simbrief. Maybe that has something to do with it?
Cheers!
Martin
