Im using a dualshock4 on windows 10 64bit with the newest ds4 windows driver.
It was all fine but since I had a coop session, some configs broke the game, not only the fresh savegame slot I used for coop. When I play now and press X, the game will ask me if player 2 wants to join. It doesnt check that I am player 1 already.

Assign the controller in the options didnt help anything...

Is there some config around I can delete ? Cant find it.

edit:
Solved, solution is to not run any second driver in the background
