Windows Defender getting alerted with Yellow Symbol again after Windows 11 update

Getting alerted with Yellow Symbol in Windows Security App​

I am using Windows 11 Pro 21H2 build 22000.978 on desktop.
I am getting Yellow Alert Symbol on Windows Security (Windows Defender), on taskbar right corner.
I have opened Windows Security, and all is green check marks.
This is the second time this has happened after a MS Update.
1st time the triangle magically disappeared after a day or so.
Now it did it again after I updated Win 11 yesterday.
Oh. I'm using Malwarebytes as my active checker and last time totally uninstalled it and didn't resolve the Yellow Symbol on MS Defender icon.

I researched and found this happens to many over the past few years and wondered why and how to correct.
Any suggestions?
Thank you.

For me the yellow alert was also in Windows Security when I opened it. It was a perfectly valid message that Memory Integrity was currently turned off, with a 'Dismiss' option. This particular machine requires drivers that are not compatible with Memory Integrity, so I dismissed it and everything went back to green.

Thanks for the suggestion but it didn't work for me.
My PC it was ON so I tried and cycled it OFF then rebooted with no change.
Turned back ON and rebooted and still an alert symbol.

Try a Reset or a Repair.

Memory integrity is anyway just microsofts way to force driver vendors to pay for officially signed drivers

Thanks Bree resetting Windows Security APP like you suggested above and rebooting worked.
Now I will remember next time to try the obvious.

do you mean the ! mark?
App & browser setting has gone AWOL
From search type APP & browser control and turn on reputation based protection

That got rid of mine

It's back doing what it did originally in 1st initial thread.
Now I have tried reseting Windows Security App like I did initally but this time after rebooting no change.
So the issue has been lurking in the background.
Scanned for virus, trojans, etc and clean.
I have search and found others with similiar issue and no solution yet.
Open for any further suggestions.

Mine too but it's just a bug? but I'm Not worried about it

I get that after some Version Upgrades and Build updates to them, usually wants a Quick Scan or take action on OneDrive which I dismiss [don't need it yet] or some other item in Windows Security.

I saw the same and it wanted me to turn 'Memory Integrity'... turned it on, no more yellow triangle.
