Windows Security won't open on Windows 11

I have tried everything I can think of, I've had two friends who deal with IT problems look at my computer via shared screen with no luck. Since updating to Windows 11 I never noticed Windows Security would not open until recently, it's active and running in the background in Task Manager. I've tried the Powershell and CMD hotfixes, I've reset my PC locally and cloud but I have no restore or recovery points prior to the Windows 11 update. My PC is up to date on all firmware from Microsoft but Windows Security still will not open. Windows Security nor Windows Defender is not listed under my "Installed Apps" or "Default Apps" so I can't try a drop down repair on it. It does show within my Task Manager that there is Windows Defender engine running and in the hidden icons tab it shows Windows Security active. How do you fix this without having to lug your whole PC to a shop?
