[Austin W Hogan]

I think you may have trouble because the trigger plate and frame were separated when you began to release the bolt. Try to put the frame back into the stock, and the trigger plate back into the frame. A few gentle taps may be necessary.
The bolt will hang up if it has side force. Try giving it a tap with a dowel. The lifter button
and cam should slide freely out of the trigger plate releasing the rest of the parts.

Best, Austin
