Hi, I've also made an account because this was the only place I could find anyone with the same problem!! I'm also running Windows 10 and it updated on Friday and ever since my keyboard has stopped working in GTA V if I plug my xbox 1 controller in. The keyboard still works if I don't use the controller, so my issue is similar to this one but not quite the same. I don't use mods but would really appreciate it if anybody has an answer for this!
