No mouse/keyboard input works
So, the solution is to restart your computer, it fixes the issue.
Rebuilding the game, deleting the config, and changing your graphic card settings do nothing as a heads up.
I'm not sure what caused the issue, but I just lost a game because of it, since I could not move or open any menus. So anyone else googling, don't bother doing anything but restarting your computer and seeing if that fixes it first. [sg-zephyr]
