I just had the same problem with 1.0.8, FMC freezing during setup and I had to restart the flight. I'll think to check for wasm in debug menu next time. I also hope the connection between the radio and beyond atc will be fix soon...
Anyway, it's a great aircraft, very enjoyable to fly. Thanks to the devs for the hard work !
EDIT: Wrong topic, I use it on MSFS2024...
