So as I. I saw a video on youtube that the only way to totally fix it is to reinstall Windows 11 or some alternative methods but it did not work for me. Fix empty Windows 11 Security or Defender App - YouTube

@Klevy I also reinstalled mine by installing the ISO file from windows 11 a couple days too. I didn't do it by having a USB drive I just did it with the setup.exe when I installed the ISO file.

Before reinstalling Windows, you may perform some basic troubleshooting steps and that would solve the issue. I advise you to open start and search for cmd or Command prompt and right click and run it as administrator and type the following command:
sfc /scannow
Press enter and let it runs.
If it detected, it find and fix corrupted files, then try open the Windows Security and see if the problem persist?
