Welcome to NICO Club!
No finger pointing or teasing please, but this happened to me once. Same as you, drivers worked, but no others. I tore into the door panels trying to figure it out. Well... I had bumped that one lock button on the driver's side controls. The one that doesn't let the passengers control their windows anymore. All I had to do was push the button again. Did you bump that button? Or, even less blame on you would be that perhaps that button is 'stuck' on the inside. Gummed up from spilt coffee or something. That could be tested with a voltmeter set to continuity.
Otherwise I've also had experience with another related issue. There are little amplifiers that look like little black boxes in the doors that control the motors. The soldered connections on those circuit boards can go bad. I was able to find mine, take it apart, find a short, re-solder the connection and that fixed it for good.
