Probleme 2 controllers in build


I have a weird probleme about local multiplayer, when i’m on the editor i can controlle correctly both player (with 2 Xbox controller), but when the game is built the 2nd player is not working anymore. It seems with some debut debug both controllers are been set correctly, so i don’t really understand why i have this probleme ;s

I also tried to add on Blueprint “SetFocus to Game Viewport”, but it don’t work.
Both players are already place in the scene, they are not create in runtime.

Thanks for the help
