Advice Request app & browser control missing!

[Cleo]

Hi MT,
I've got Win11 Pro running on a machine and today I noticed the little yellow " ! " was on the Windows Security tray with a recommendation.
However, when I open "app & browser control" it just instantly closes again. Also, "app and browser control" is now missing from the "security at a glance" page.
If I put "core isolation" in the search bar and try to open that I get the popup:

I also noticed that right of the "Device Security" leaf, it now says "Standard hardware security not supported".
I checked my BIOS and TMP, Secure Boot, UEFi & DEP are all on and have been unchanged for months.
I ran the Microsoft "PC Health Check" app the check if my Win11 PC can run Win11 and it reports all tests passed.

How should I proceed usage wise on this PC until I have time to tinker/reinstall/restore etc? How much bigger is the attack surface w/o these things working? Is it likely anything else under the hood is busted?

FYI it does seem this is a known issue to Microsoft since built 22621.

Are you running a stable OS build? Have you checked this thread?

App & Browser control section is completely missing from windows security center

Anyone else have this? Or know of a fix? I just upgraded to the beta ring in anticipation of a few welcome additions. Apparently 22621.1 is RTM and so i figured it would be a good time to get ahead of the changes and familiarize now etc. First attempt at an upgrade I came back to my PC to an...

Thanks for the links. It seems I don't have the problematic folder that they mention but I do have "send Microsoft optional diagnostic data" turned off which is the other problem that is associated with this issue. Unfortunately I've no clue how to turn it back on as this PC is saying "its under a setting managed by my organisation" and the on/off switch it greyed out.
This is a private user - personal install of Win11 Pro so it makes no sense why its saying an organisation manages it.

It seems like "app & browser control" was somehow flicked off via a Win11 glitch or 3rd party app. The problem is that "app & browser control" can now only be switched back on via a fresh windows install so I am stuck with the yellow " ! " on the Windows Security try icon until I do that. Microsoft will also switch it off for you if they determine that during an initial evaluation period after installing Windows 11 they decide that your PC is not a good candidate for "app & browser control".
I've reinstalled Windows 11 and have "app & browser control" on. Its very strict - can't install AMD automatic driver detector due to some component not having an up-to-date signature.

@Cleo "This is a private user - personal install of Win11 Pro so it makes no sense why its saying an organisation manages it."
Do you use O&O shutup 10 by chance? If you use it some of the tweaks can lead to the "organistation manged" in some parts of Windows e.g. Edge. So maybe revert your tweaks and reboot if you used it.

Or if you tweak some settings with another similar app or on your own via GPO, etc..

I don't use anything. I had Avira, office, amd suite, intel assistant, adguard and a few browser extensions for edge. A fairly barebone setup.
