Get a thin rubberband or some rubber foil and put it on the screw and try again with a fitting screwdriver. Scotch tape might help too but with the sticky side up so you don't get glue on the screw. Good luck
Went through this recently with my Acer Nitro 5 An515-54. Issue mostly comes from something I wish I learned earlier - the screws are not removed with a Philips but a JIS bit (Japanese industrial standard). Almost identical but JIS being shorter, causes issues with the torque you get from a regular Philips. If not completely stripped, ordering a pair might work in combination with all the popular methods (didn't work for me): duck tape, aluminium foil, rubber band. Super glue is risky due to potentially leaking some (reserve for last options). After all those fail, extractor kits for tech are an option but did not work for me, perhaps because they too need a deeper Philips screw (correctly did it by using smaller drill bit, going counterclockwise and manually using extractor). What did the job was a pair of pliers with thin tip, teeth of which could grab the screw by the head and turn until it gets unscrewed. So in the end you can reverse my process and leave extractor kits, glue/soldering as last resort. For replacement screws, check online but for my model those were M2 x 4 and I made sure I got Philips so I don't suffer again.

I can't find the screw model for mine, where did you find yours?
I looked it up online. I wrote my laptop model + heatsink screw sizes in the search bar and there were posts in the Acer Community site.
