I am on PC but It looks like you are on xbox so it can’t be the FBW A320,correct? for the same reason you haven’t installed any mod (many times they are the culprit).I have no problems on the Asobo A320.At this point I believe a reinstall would be the only solution for you.
Edit : unless you have installed the OLD FBW A320 that was available on the market place for free.If positive you must remove it from the Content.This version ,not more supported by FBW , will cause a lot of conflict s to the Asobo one’s.
