Windows 10: Device Security->Core Isolation has yellow triangle with exclamation point

Win 11. Settings->Privacy&Security->Windows Security->Core Isolation says"Local Security Authority protection is off. Your device may be vulnerable."I can see no obvious action to take to fix this. What should I do?

Device Security - Yellow Triangle!

Something I installed must have also installed Norton 360. I uninstalled, rebooted,, then noticed a shiels with a yellow triangle in my hidden icons on the taskbar. I click and it takes me to Security at a glance. Inder Device Security there is a yellow triangle & it says "Local Security Authority protection is off. Your device may be vulnerable". I click on Go to settings and get this message, "Page not available. The page you are trying to access has no supported features and is not available."

Is this something I should be concerned about?

Error Message: Exclamation Point in Yellow Triangle

I have an exclamation point in a yellow triangle next to my name in Word. I received a message saying that there was a problem with my account, and asking whether I wanted to start up Word in Safe Mode. I answered yes, and this message was in my Word document,
next to my name. When I click on my name, the message says, "ACCOUNT ERROR Sorry, we can't get to your account right now. To fix this, please sign in again." I've never seen this message before, and I just updated Office from a pop-up a couple of days ago.
Is there any danger in signing in again? Thanks for any information.
