The Local Security Authority protection is off - Windows 11 Home

A yellow triangle appeared on the Windows Security iron yesterday. It says that Local Security Authority protection is off. Your device may be vulnerable.

I can press Go to settings or Dismiss but when I click go to settings, a notification saying "the page You want to access doesn't contain required functions and is unavailable". 

There is also no option to turn the protection on in the Device Security panel (there is only "dismiss" option).

When I was looking at it yesterday, there was also a notification that "The tpm module is unavailable" but today it doesn't show. I checked the device manager and uefi and both say that the tpm is enabled.

I've found an advice to turn on SMV in UEFI (in the CPU settings) to solve the problem but I don't want to change anything in BIOS without consultation as I'm no expert. I've also found a reply from a truste source that this whole problem is a Microsoft bug and it's better to just wait till they fix it.

What should I do?

Screenshots are in Polish, I hope they can be useful somehow. The first one shows the notification about a page being not available and the second shows the Device security panel (the notification from the first screenshot displays when I close the device security page or when I click on "go to settings" below the information that the protection is turned off). There is also an information (second screenshot) that "standard device security is not supported".

Microsoft have just posted that they have resolved the "Local Security Authority protection is off" issue in an update. Has anyone tried to apply it from Windows Update?

Resolution: This issue was resolved in an update for Windows Security platform antimalware platform KB5007651 (Version 1.0.2306.10002). If you would like to install the update before it is installed automatically, you will need to check for updates.

    Same exact method as the 1st time which said was successful, but still had the Exclamation Mark!. Rebooted several times while changing values to 1 and back to 2. Noticed RunAsPPLBoot was missing. Ran both RegEdit strings, even though RunAsPPL (2) already existed. Rebooted again, and viola. So if this is what your CurrentControlSet\Control\Lsa RegKey Directory looks like, you should be good.
