System Security doesn't exist!

I have warnings of Actions Recommended by Windows Security on my newly installed Windows 11 VM (release 22623.1245), but Windows Security doesn't exist! System Settings/Privacy & Security/Open Windows Security says "Get an app to open this 'windowsdefender 'link. And none of the context entries from the recommendations icon in the taskbar do anything different.

I have tried all the solutions I could find -
commands including Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage;
commands;
SFC /SCANNOW;
reboots;
checking Windows Defender regedit entries

and nothing works! What's wrong that such a basic thing doesn't;t work on a new system install? I hope you can help me, thanks!!
