I had this problem since SU6. I had to update the bindings on my controller to fix. I am using the Thrustmaster Airbus sidestick and throttle. I am running my first flight on SU7 using thelatest A320NX (Dev build) as I write this without any issues so far. There are some posts on here regarding updating the profile for your side stick and throttle if you are using the Thurstmaster airbus controls.
