Keyboard commands not recognized

After this update my keyboard cannot control the character. i look at my control options and I only have the gamepad controls. The keyboard and Alternate keyboard commands are “unassigned” I can’t assign any and can’t go back to my defaults either. Tried to delete the game and reinstall but it is the same. Is there a preferences file on my computer? What is the name of it?
