System.ComponentModel.Win32Exception (0x80090302): The function requested is not supported at System.Net.NTAuthentication.GetOutgoingBlob(Byte[] incomingBlob, Boolean throwOnError, SecurityStatusPal& statusCode)

This is occurring with a win2016 machine loaded with 2.2.203 sourced binaries and installed with asp.net core 2.2.4.

Occurs when networkcredential are loaded into httpclienthandler.credentials

This seems to only occur when network credentials are expected to be transmitted to the receiving end.

can you craft simple corefx repro? Can you reproduce it without asp.net? This is not actionable as written.

Closing as not-actionable due to not having a repro.
