Stripped screw, how to get rid of it completely?

Took my 3ds to 4 different repair shops, first three couldn’t do anything, last one was able to pry the casing off for further repairs.

Anyways, the screw is still there, but I just can’t for the life of me get this thing out, even with both sides exposed now. It wobbles and stuff, but I’m unable to twist it with tweezers.

Anyone have a similar experience and fix it?
