Dig the grot out of the screw head first of all so a screwdriver can properly bite into it. Get the correct size screwdriver and apply as much pressure as you can when turning. If you can, use a good quality screwdriver such as wera, which have abrasive tips to help grip. A fine lapping paste can also help grip if you don’t have wera/don’t want to spend out on wera screwdriver for one job.
Use a penetrating fluid but it might not do much as it’s probably screwed straight in to plastic.
Ideally replace it when you get it out with a clean screw or clean this one up and grease it to stop it corroding so badly in the future.
