@wfurt Looking at tests failing with the same message, I see the first occurrence on #88970, with many more starting Aug 1st, when it was merged.

Example failure:

Assert.Equal() Failure
Expected: 127.0.0.1:63379
Actual:   0.0.0.0:0
   at System.Net.Sockets.Tests.ReceiveFrom`1.ReceiveSent_UDP_Success(Boolean ipv4) in /_/src/libraries/System.Net.Sockets/tests/FunctionalTests/ReceiveFrom.cs:line 153

runtime/src/libraries/System.Net.Sockets/tests/FunctionalTests/ReceiveFrom.cs

Line 153 in a0d7531

Assert.Equal(sender.LocalEndPoint, result.RemoteEndPoint);

Seems to be passing on reruns most of the time
