Sorry for inconvenience to you.
You can place a rubber band over the screw head and press the band with your screwdriver while twisting. The rubber band increases friction between the screwdriver and the screw head, preventing slippage and aiding in unscrewing the screw.
You can also use strong tape, such as electrical tape, to cover the screw head and then insert the screwdriver and try to turn it.
If you still can’t unscrew it, you can try to seek help from a nearby repair shop.
