It’s mounted right up tight to the beam, so I don’t think it will snap in
I don’t have one, maybe I could chip some wood away in order to snap it in. Any other ideas?
OK so how is it you are aware of an open KO?
Just widdle it out a bit with a paddle bit. She'll pop right in...
I agree. Boxes are often mounted by removing a KO and using a fender washer to close the KO.

All solutions presented require pulling the chandelier, the OP didn't want to do that.
How is it you are aware of the open KO if you haven't already pulled the chandelier?
My solution did not require him to remove anything. Just get a fender washer big enough to cover the hole and a wood screw.
I had to fix a loose connection that I found, so I loosened the nut that slides down the chandelier chain which drops the canopy which then exposed the box
So you had access to the missing KO. Your initial idea of a screw and fender washer is fine.
The box is mounted directly to a wood framing member so the KO cannot use any type of seal that needs to go through the KO. You could take the 3 piece KO seal in your photo and throw away the bracket and the screw and just use a wood screw.
Ok. Then any of the suggestions might work. Closure requirement per code (NEC 110.12(A)) is only that what ever is used is equivalent to the box wall properties. I would even think another KO removed from a different box and drill a small hole big enough for a screw and screw it in.
