Can't add script problem

Hello, I have a scripting problem: When I try to add a scipt, it ask me to name the script so I name it and I press Enter but it add me an invisible entity without icon and name, look at the screenshot, and when I try to edit the script, it open a blank page in Visual Studio. So I cant add any script! I reinstalled Unity and I also changed the version but it still don’t work, p134701-capture.pnglease help me.

I resolved the problem! My antivirus was blocking the scipt creation because my project was in a protected location, so I just changed my project location.
