deathadder V2 Pro comes and goes by itself

First of all hello, I bought a deathadder V2 Pro about 2 years ago and now I noticed that the mouse moves back and forth during the game and I am very disturbed by this situation, it was not a problem before.And now I understand that when I hold the mouse upside down and try to shoot someone while in the game, it suddenly disconnects and comes back, please help me.
