Exception when creating new game

[tewarid]

I cloned this repo, and updated the Windows 10 target version to 2004 (build 19041) when prompted by Visual Studio. Running the app and trying to create a new game results in the following exception

System.Runtime.InteropServices.COMException
  HResult=0x8007271D
  Message=An attempt was made to access a socket in a way forbidden by its access permissions.
