This is going to be tricky.
If any of the linkages are stuck, the latch would not work. Ensure outer handle and inner handle fully returns to position. Pull up locking knob. Pull at outer door handle and ensure the latch is in the fully released position (unlatched), if latch is in closed position, use a screwdriver to release it. Release door handle and retest.
If it fails to work, you would need to remove the door panel to check the linkages.
