Had this happen to me today too. I loaded up AMS for the first time this morning, setup all the controls, options etc, did one lap on track to test and make sure everything was fine. and it was. Load up this afternoon and jump straight onto the track. No steering wheel controls and no keyboard (can't press esc to exit the track). Re-checking the control settings it seems as though my steering wheel is now considered input device 3 instead of input 4 like it was earlier and I have no idea what happened to the keyboard. If I unplug my xbox 1 controller it seems fine, with it plugged in, I have no keyboard.
