Issues with Windows Security Defender Antivirus

Hello,



A few days ago, I noticed that the "Cloud-delivered protection" and "Automatic sample submission" options in Defender are greyed out, with the message "This setting is managed by your administrator" displayed in red above them. Incidentally, I *am* the administrator—please see the attached image.



I have two operating systems running Windows 11; the settings are fine on the second one, but not on my primary system, and this is bothering me. I would appreciate help on how to fix this. Resetting the Defender application itself doesn't solve the issue, nor does reinstalling the system via Windows Update. I’ve already tried a few things—including using AI—but without success. It appears to be a setting that is locked in the registry.



Please help.
