Can you open the door ahead of stuck door an see the hinge bolt and nut?if so remove nut and bolts lower first have someone hold door and remove top bolt door will move toward hinge and push out and open. Then remove latch from inside you'll probably find that 1 loose screw that's supposed to pull latch back,I removed that screw and applied a drop of lock tight. It's a pain to get the hinge bolts out,but it can be done. Then I put lock tight on the rest of the offending screw on all latches.
