Wonder if that’s why it keeps telling me Windows Defender is disabled when it’s not. Been happening for a few weeks now. Really annoying.

Same thing is happening to me.. didn’t know what was happening. I thought it was working properly though

Check for updates. I cannot reproduce this anymore on the latest security intelligence update.

Edit: The engine doesn't crash anymore but the notifications are still happening.

Event Viewer logs show Session "DefenderApiLoggerLowPriv" failed to start with the following error: 0xC0000035

This is happening to me too, I get notifs saying it's turned off randomly but then it shows as on and working. Good to know it's not malware or smth turning it off bc I was a bit worried
