windows defender is not working after updating from windows 11. Some system files (.dll) Files went missing automatically. I tried every troubleshooting measure i could but am not being able to solve the issue. I also contacted the microsoft support but issue remained same. Therefore i need live support for solving this issue i you can provide.
