A350 is behaving strange mid flight

[BenAura]

After a few hours of flight my a350 wanted to go Mach 0.00, all times in the Flightplan page are -596505:37, the display was constantly showing "Nav accur downgraded", the side perspective of the flightpath isn't showed, over Canada it just flew like it wanted (160 miles next to the flightpath and in the opposite direction), after a few failed attempts to disconnect the autopilot I restarted the game and loaded the last Autosave and the aircraft had the same issues, but i could disconnect the autopilot that wants to pull a angle of attack of 25°. Earlier Autosaves hat the same issues.

It is a WASM crash, I made a 2nd flight and after three hours I had similar issues, all screens froze and i was unable to control the aircraft, some people at this forum had the same problems. Sadly I'm unable to report the WASM crash because I'm playing on Xbox.
