Operation did not complete successfully because the file contains a virus or potentially unwanted software

When trying to open disable-defender.exe on Windows 11 Home 21H2 I'm getting this error: Operation did not complete successfully because the file contains a virus or potentially unwanted software

I tried disabling the real-time protection, but the Security at a glance screen is empty for me. Tried some solutions for the empty screen from the internet, but nothing worked.

Do you perhaps have another anti-virus running?

You can try compiling the software yourself and it should circumvent the file being tagged automatically.

And what is the problem creating a legitimate dummy Security Provider that can install like a regular antivirus and don't do nothing? Does it need a certificate from microsoft?
