For three flights going EGNX and EGSS to EDDF I have had a CTD between the VOR KOK and waypoint FERDI along airway UL607. About 14 nm out from FERDI it crashes. Using simbrief generated flight plan. I will try a direct flight next time and see if it survives. Not sure if it is ground scenery related. It is close to EBBR but I have stock streaming Brussels. Using BeyondATC and GSXpro. Currently on flight from EGNX to aerosoft ENGM without any issues in same PMDG 777F. Running 4080super on intel 14700K with all the microcode updates.
