It sounds like the door hinges have got a bit out of line, allowing the door to drop slightly, so the catch mechanism won't quite disengage. Look along the bottom edge of the door and see if it has dropped lower than the front panel next to it. Try applying a bit of upward pressure on the bottom edge with your fingers, while pulling towards you at the same time, and with your other hand press the release button.
Well I am certainly glad to hear the problem is solved. You have a great rest of your day.
