it has been confirmed by Asobo that with the recent MSFS update (13.04.2021) any stand alone WASM module will make the simulator crash.
This affects AxisAndOhs too. Please make sure to remove the folder "lorbysi-content-hooks" from your Community folder, or MSFS will crash without further notice about 10 seconds after the Update screen.
The app itself will work normally, but you will lose access to the internal LVars and HVars.
Asobo have promised to fix the problem as soon as possible.
