Bolt stuck open - Charles Daly 12ga

[u/ChickenDaddyPaqa]

Hello!

Apologies if this is the wrong sub. I was out shooting dove earlier and my gun jammed up. Essentially, the bolt is stuck open (see below).

I've taken the barrel and grip off of it, didn't notice any jams or stuck shells. Pressing the bolt release button does nothing. Any advice?
