    Windows Defender Won't Open


    Hello!


    Just a quick question for the community. I have ran into a problem with Windows Defender. When I go to Settings > Windows Security, I can't open Windows Defender. All it says is that "You'll need a new app to open this windowsdefender." I've looked over the forum and asked the help bot to no avail.


    Can anyone give me some insight or help on whats happening? Thank you.
