It is easy to repeat this error
1. Start a free flight game from a runway, and fly the aircraft off the ground.
2. Press ESC on the keyboard and select "Restart"
3. After the game restarted, the WASM crash occurred.

WASM crash

Edited December 6, 2025Dec 6 by hu hu

 

I've tried many flights with the v1.0.5 on SU4 and all of them result to a WASM Crash with the red gauges. I can't complete even a single flight. Most of the time when manipulating the MCDU for normal stuff. It's really annoying to start a flight and being stress about a crash at any Time. 

Until next update I won't reinstall the aircraft as it is just not playable.

Hopping for a Hot Fix soon.

 

Regards
