Thank you! This did the trick for me! FWIW, I was logged in as an administrator user and ran in an admin command prompt.

2022-05-10T02:04:24+00:00 This is the exact problem I'm having. My main admin account is fine, never had a single issue.
My secondary accounts (wife and child sub accounts with no admin access) have the same problem. There's an exclamation point on the Windows Security shield stating that Action needs addressed. I can't get rid of it. I can't open Microsoft Security. Everything is patched / up to date, but I'm unable to run scans.
