Can't perform forward actions

Hello ! I had such a problem when I move forward and try, for example, to make a somersault in the same direction, that is, W + Space, then nothing but a simple movement happens, the character runs as he ran. Also if I hold down W and try to go right or left, but he just keeps going forward. And the whole problem is precisely during the movement forward, somersaults to the sides work and everything else seems to work too.
