It was previously mentioned that the issue occurred after updating, but not which updates so I wanted to add that information in case it helps figuring out this issue.On Windows, there's commonly no thing like a package manager as on (most?) linux systems. I blocked this update, but today I experienced the same issue with KB5016616. When my laptop installed KB5015807 I immediately noticed the issue of UDP packets missing. What I wanted to note is this started with KB5015807.
