For stripped screws there are tools called 'stripped screw extractor' or 'spiral screw extractor' or 'speed out' or 'easy out'. There are a few different forms of the tool but they do the same thing: bite into the metal of the screw so you can unscrew it. They aren't expensive, you can find them on Amazon or other places. Make sure to get a set that has a very small one and you should be able to get the screw out. Then buy a pack of replacement SSD screws (you can also get those on Amazon) and you should be good.
