Standard asset : Third person character dont want to jump?

Hello,im trying to create a third person rpg game for test purpose!
I took the standard third person character asset and change the animations + the model.
Everything worked so far :
gif(idle,walking,running and jumping)

Now i want my character to switch the grounded and crouching animations after i pressed q and if i press q again it should switch back to my normal animations.
(guess my explanation is kind of bad? but the gif should explain it pretty good)

So,as you can see see switchting between "no weapon" and the "with weapon" animation works aswell. But somehow my character cant jump when he switched to the" with weapon" animations

My animator :

Grounded 0,crouching 0 and airborne 1 is the same as the normal animation,i just replaced it with different animations.

Parameter are the same as the standard assets + a boolean called "keyx"

Code to switch between "no weapon" and "weapon"

 f (Input.GetKeyDown (KeyCode.Q)) {
                 if (myAnimator.GetBool ("keyx") == false) {
                     myAnimator.SetBool ("keyx", true);
                 
                 } else if (myAnimator.GetBool ("keyx") == true) {
                     myAnimator.SetBool ("keyx", false);
                     
                 }
 
             }
  

My first throught was that the "with weapon" animations are kind of bugged or smth like that but if i change the "no weapon animations"(where jumping etc works) with "with weapon animation" it works. So the animations are fine,but i still cant figure out why it doesnt work after i changed to the "with weapon" animations.

Hopefully u understand my problem,english isnt my native language,i tried my best.
