Ps4 screw is not on the back?

As the question reveals, a screw on the back of my Ps4 does not go out. Wanted to clean it but this one screw prevents me from doing it, which is very annoying. The other screws I get out with the Torx screwdriver without problems only this one annoying. Does anyone know what I could do?

For that you need another special one. Which I do not know, I was told so.

I told you that I can get all the screws out except one that is scratched.
