Nothing happens when this user tries to start the app. We mentioned below are the ways to Fix When Windows Defender Won’t Open on Windows 11.
Ways to Fix When Windows Defender Won’t Open on Windows 11
Reset or Repair Windows Security
A built-in repair tool in Windows 11 may automatically find and fix minor problems in apps. This is also true with Windows Security. How to do it is as follows:
Use SFC and DISM
Corrupted or altered data might cause some Windows 11 applications to stop functioning, including Windows Security. Fortunately, you can find and restore these files with the correct version using the SFC (System File Checker) and DISM (Deployment Image Servicing and Management) tools.
Disable Background Apps
Background processes that are not required can obstruct Windows Security. Use Task Manager to force these processes to terminate if you think this might be the problem. Additionally, you can conduct a clean boot to ensure that Windows Security is not hampered.
