Need to use a new application to open the windowsdefender link

[admin]

In the 1909 system, you may encounter errors reported by the Security Center. When you open the Windows Security Center, the message "Need to use a new application to open this windows defender link." This indicates that the Windows security application is damaged, so the link is not working properly. Of course, there is no application in the Microsoft Store that can handle this application. If you are also a victim of this issue, please try the suggestions mentioned below and see if they help.
