If your controller is plugged in then the keyboard won't be recognized. Make sure any sort of controller isn't plugged it when you run it!
I don't even have a controller
Something in one of your USB ports is being registered as a controller. Is there any weird peripherals plugged in?
I don't think so
Actually, I think my headphones are regestering as a controller
Nope
Do you have anything bluetooth connected or anything besides the keyboard and mouse?
Yes. I fixed it. Thanks
I'll try to get back to you as soon as possible on the gameplay
