Help my rigidbody2d is freezing

Can someone please help me so I added a Fixedjoint2d on my rigidbody2d and set it to false on void start and every time I drag and shoot my player it will stay false I also added some code that turns on the fixedjoint2d sticking my player to a collision2d whenever it collides with a collision2d but after dragging and shooting my rigidbody2d when it's stuck to a collision2d it moves then freezes in place but if I drag and shoot again it works can anyone help me fix it so that it can shoot off the collision2d without freezing this is my code so far
