The most likely cause of this is a detached spring on the release lever. Inside the gun, there is a spring that retracts the release lever after every shot. If this spring is detached or faulty, it will not return the lever to its original position.
This lever is also what the loading pull lever latches onto when you load the gun. Once the spring is reattached, then the release lever will function properly again, allowing you to load the gun.
