This is an issue since the recent update 1.0.2306.10002. Right-clicking the icon does nothing but left-clicking opens the Security window

My hopes were raised when the recent update to the Anti Malware Platform kb5007651 Ver 1.0.2306.10002 was installed but no luck. Still broken.

@Mitch So you have the same issue? Well in my post above #3.... I guess I'll have to use that route. Until I get a reply on this matter. Cheers

This issue has a long tail. The irritating thing is that I don't use Defender but Norton 360 which, when installed takes over and shuts off Defender. However, Windows Update persists in downloading definitions including this rogue update. You might also find that when you try to open Windows Security Centre the app crashes and an error shows in Event Viewer/Reliabilty Monitor. The Windows Health Centre service probably stopped and restarted after 1 minute. BTW, there is another thread on this issue

Windows Security Health Crash after Windows 11 22H2 Upgrade​

Hope this helps,
Mitch.

Thanks for the reply ! I've had no crashes or errors - none in the event viewer. I see on the forum, alot of other users with the same issue as mine.
I sent my issue to an MS forum. Only to find the problem was worse on the MS forum. Will be back. I have grandkids here today. Cheers

It's MS being MS unfortunately. Until they decide to fix it there's not much we can do
