"Turn on Virus Protection" Notification appears after the latest update

So after the latest Windows 11 update I constantly get a single notification from Windows Defender claiming that it was turned off and suggesting to "Turn on Virus Protection". Fun fact is that Defender keeps working all the time and never turns off. Another fun fact is that the notification appears at the same exact time, 4m13sec after logging into account (judging by task manager uptime timer). I've heard a similar story from another user experiencing the same issue after latest update, but for him the notification appears at 4m23sec. 

I contacted support and they said that they might require multiple feedbacks on this issue from different users to confirm that it's a bug. While my PC was checked by Microsoft support team member and he confirmed that there's no issue with my system. Everything runs perfectly fine and working as it should. 

From the side it looks like it's some scheduled event bug, however upon checking task scheduler there was nothing to trigger this notification. As well as event manager shows no visible signs of critical errors on that matter (or at least I don't see any).

It's extremely concerning to me, cause it's the first issue related to Windows Security which happened to me since my first day of using Windows 11. And there's no trace of it, so basically it's unable to identify the source of this bug.

Reinstalling system helped for a while, but after several hours a few minor security updates were installed, and the notification came back. Like i said, it appears only once after each account log in. If my PC goes to sleep, I can wake it up as many times as I want and it won't show it ever again.

Can anyone confirm the same weird behavior after the latest updates? If so, is anyone willing to send a feedback?
