Hello there,
I too experince a frozen XP11, although it usually takes somewhat longer than in Jerry's case.
This a C&P from the log:

I don't know if it matters at all, but it would appear that the incidents happen sooner in the Just Flight Piper Arrow III than in the modded BE58 (Double Trouble + 4K textures + GTN).
This log is from the latest flight in the Arrow III which I forgot to time, but maybe north of a couple of hours. I tried something new today. Started Cold and Dark, disengaged GTN in Plugin mamager, powered up (incl switching on the GNS530) and re enabled the GTN that then powered up after a moment.
