I have a thrustmaster too - did you ‘calibrate’ the joystick in Windows? if so - reset to default and apply - then reopen MSFS and reset all JS settings and bindings to default and save settings. Close MSFS and restart your PC - then open MSFS and test the controller with a flight.
If the problem is resolved you can reset any non-default bindings you like. but test each one.
Also - you will want to remove any and ALL other RUDDER related key bindings in your keyboard profile of MSFS. There can be no other potential conflict with the JS wrt rudder inputs
