I have not used a 3rd party AV in years.
Defender works well enough and my family members are smart enough to not just click on stuff. So no real big issues with another 3rd party app being blocked from my systems

This wasn't a Windows update that caused the issue, but a Windows Defender security update.
Not that this get MS off the hook, but does show your lack of comprehension of what you skipped over for the joy of a snarky comment.
But whatever.
