Run SFC and DISM

If your file system has problems, the built-in components of Windows 11, such as Windows Security, will not be able to run. Therefore, you should try using automatic system file checking and fixing tools such as System File Checker (SFC) and Deployment Image Servicing and Management (DISM). The specifics are as follows:

Step 1 : Press the Start button then enter cmd to search.

Step 2: Right-click Command Prompt and select Run as administrator .
