How to fix: Mouse and/or keyboard don't work in game

It does fix the problem, but if  I disable the overlay im not able to join my friends lobby... 

THANK YOU FOR SAYING THIS. I AM ALSO WONDERING HOW DO YOU GET FRIENDS TO JOIN YOU BECAUSE WHEN YOU DISABLE THE OVERLAY YOU CANT JOIN A PARTY

Hello Mr. HERO. Did this procedure work out for everybody?

Did anybody compile a final working set of steps anybody could follow?

that doesnt fix my problem

i did fix it i guess

okay so, im like 4 years late and hopefully you reply BUT, im experiencing this problem but with a different game (sims 4). I already tried a new mouse and it still didnt work. the problem im having is that whenever I move the mouse in the game it freezes in place and doesnt move until it wants to and it is pissing me off…I JUST WANT TO PLAY. the mouse works properly outside of games but freezes and glitches and overall just doesn’t work inside of games, so I cant play at all. this also happened with roblox…so I dont know if its my laptop or the games. please help.

In Battlefront 2, the issue for me was a missing driver for the wireless controller. Without it, when opening the game, at the menu it looked like it recognizes a xbox controller and clicks wherever whenever. When installed, it resolved it without needing to close the overlay. Hope it might be similar for sims. Bless ya.

If u have the NVidia GD then u need to disable that overlay
