I have newest MSFS2020 and fnx320, and here are logs.

disconnected from SimConnect.
//finally i exit the sim.
and also, I had tried installer from topic(after use the live update to updater's newest), and no live update in all operation except in installation, it's dosenot work. the problem persist.
there also some exception info in log, but i dont know will it affect menu function.
i'm also thanks to all who develops GSX,
but as a user, I may feel very tired to search whole Internet and try to fina a wayout.
and finally, as a programer, I know that there are many unknown questions between 3rd and MSFS2020, but i also want a flexible experience in past, like FSX or P3D.
Hope FS Dream Team can give a good Dream Trip in game.
Thanks to all who develops GSX.
