"Windows 11 Pro 22000.918
Clean installed ->>> same Issue."
I'm on 22000.918 home with a recent clean install and its there by simply going to settings > security. The main post doesn't specify which Windows 11 so it seems unrelated to pro.
Seems to me like there's some other reason. Either way, its there for others in a normal way.
I guess you might as well wait some time regardless and see how it goes lol.
I'd hate to say your Windows installation is already corrupted. So it may just be a code issue.
