[BUG] help! character moves on his own

https://reddit.com/link/1hsivox/video/ewwodlqr1rae1/player

I was doing khorovod mode with other people

And when you do the transit and you spawn, the character starts to move at will

The button is input, but I can't control it at will and I couldn't solve it by pressing the alt-tab button on the keyboard or a button for other actions

I'm very angry because I've died three times because of these bugs. But I couldn't find a solution through Googling

I need your help
