I know this sounds strange, but it just happened to me twice, once in 1.0.8 and the recent one also in 1.0.9.
Steps to reproduce:
1. start flight in cold and dark and setup as usual,
2. take-off and fly to cruise , turn on AP
3. insert the hoppie logon in EFB and use the ATC/COMM page to notify and request some D-ATIS
4. turn on auto time compression and set up to 4x
5. wait for the issue
When this happens, all the avionics or flight control not working, in detail:
- you can still click the button to switch pages, but all MFD page show blank.
- all the MCP panel buttons and knobs are not responsed
- the aircraft when out of control and starting banking left, all the input from my Yoke/throttle/Rudder can not take back the control
The first time I do saw a WASM crash message in the debug console, but the most recent one it shows nothing, 0 error messages.
This only happened when I use Hoppie logon, without the hoppie, I tested many flights and none of them had same issue.
BTW, I loaded the autosaved one after the crash, and immediately removed the Hoppie logon code, after that, the same flight safely unitl landing on destination and shutdown.
