Usually once per today, while doing nothing, I get the pop up that module is blocked from loading into LSA, and its a folder Bonjour/mdnsNSP.dll.

Does anyone know how to fix this? What is happening. Thanks

    I ended up running this in PowerShell as an administrator.

    winget uninstall bonjour

    then

    winget install apple.bonjour

    There seems to be 2 bonjour packages available. Bonjour Paris! from msstoe and Bonjour(apple.bonjuor). I just picked one.

    Havent had the error in a few days now

    I was experiencing the same problem. I do not have iTunes installed, but I found Bounjour following these instructions. I disabled it, re-started and the error no longer appears.

    My name is Jonathan Deives. I'm an Independent Advisor and I will be happy to help you.

    This pop-up usually appears because of the iTunes app. Do you have it installed?

    If so, temporarily uninstall it to see if the problem persists.

    running OBS (Open Broadcaster Software) seems to also trigger this same issue/warning.

    I second that. Running a previously stable system. Installed OBS Studio on 5/2, and have been getting the error ever since. Just tried the winget upgrade, so we'll see if that fixes things.
