What do you mean by stuck? Do you mean that when you push one of the pedals it continues in that direction even when you relax pressure? Perhaps you mean the toe brakes are latching on or even reversed?
I suspect you have an assignment wrong somewhere. Essentially their are three axes:
Rudder
Left toe brake
Right toe brake
In the controllers screen ensure that these are all bound to an “axis”, and are not assigned to a digital, on or off, binding.
If in doubt please post images of your bindings here so we can see.
