I keep on getting "Controller not found" and it's ruining my entire PC


This is what pops up. It disconnects my mouse even if the game isnt on. I NEED a way to stop it. It’s ruining EVERYTHING I do on my computer

Here is what it looks like. Anytime my mouse is not moving (you can see it hovering over those locked techtree vehicles), its disconnected and I can’t to ANYTHING. It’s a pain for gaming, for my fucking work and for anything inbetween. i’ve tried some stuff, nothing worked. I geniuenly need help
