Original DS screw post broke and stops it from opening.

I have an original Nintendo DS that I am doing a shell swap on because the old shell has become yellowed and really brittle. It’s literally crumbling away as I touch it. I was taking off the bottom piece of the shell, but one of the screw posts broke and it’s blocking it from opening. I can’t get the screw out and the post won’t fit through the whole in the motherboard because it’s too wide on the end with the broken plastic. I tried to cut it but my flush cutters won’t fit in the small space I can open it. I don’t want to break the bottom shell piece because it’s in good condition and not brittle. If anyone has any ideas on how to get it out I would be eternally grateful.

I’ll attach an image so you can see what I’m dealing with. (Sorry they’re not that good it was hard to take the photos.

Thank you for your help. I appreciate any answer than can help me get this thing open.
