I have a similar issue, on my hinges there is a little plastic piece lining the arm that like to break off and cause this. Similar vintage house and hinge type.

I still haven’t been able to track down the make/model to even find out if the piece is serviceable or not. I’m using those little hard Velcro strips until enough break to warrant new hardware.

I see the ribs dude, but what I’m really eyeing is that “kitchen hatchet?” on the board.
