Nintendo Switch broken screw housings help.

Hello everyone. I hope someone can help repairing physical damage on my Switch.

Basically some of the screw housings have become damaged, so a few screws will no longer stay in.

Also the screws on the top of the backplate will seem to push away if I try to tighten them (while using extra gentle pressure).

The damage is causing the backplate to peel off from the top.

So any advice on how to repair broken screw housings or any alternative ideas to fix it would be greatly appreciated. Please let me know if additional pics are needed.

Thank you.
