SU6 and No assignation Keys and No puissance Power Aircraft!

Hi ! While I had a 2020 MSFS that was working properly, I found myself with the SU6 with a problem that I cannot fix !
The key assignments are almost ineffective !

The engines are almost at maximum before “starting the flight” !!!
And once the flight has started, the plane advances on the runway without the engine power making it take off !
The Joystick does not work ! While the “inverted” box is not checked, the throttle is inverted !
