I see a serious color issues with the baffle. It should be as bright and shiny as the bolt head.

Either corrosion, goo or unknown, but that would explain why it does not turn freely.

You need to take the bolt apart and clean it up, but you also need to figure out what is causing that crud.
The firing pin has to come out to take that off so you need to work from the back forward. ie. complete bolt disassembly.

Fin a U Tube, while its not really tricky, it has to be done right in the right order.

Not trying to be rude, but as you did not recognize the misalignment you may want to take the bolt to a gun smith to have worked on.

As the bolt looks ok ad does the head, it seems baffle specific and that is (pun intended) baffling.

there is a story there that needs to be told.

When done it should turn easily with little fingers.
