Good evening, when I fly the A350 in MSFS2020, I'm experiencing an issue on long flights (over 6 hours) where, while using the FMS1, all the instruments freeze. I can deactivate the autopilot with the joystick and fly manually, but the power, landing gear, flaps, etc., are unresponsive. Has this issue been reported before? Or can anyone tell me how to fix it?
