As several have pointed out, the problem is that the ball has drifted to the back of the coupler, so the moving piece won't move. My driveway slopes slightly and I experienced this problerm. To figure out what was going on and what needs to happen, I laid on my back and looked up into the unhitched coupler while my wife worked the latch lever a few times. It was a real AHA! moment. You might do the same.
