The connection problem of Holographic Emulation in Unity when using Hololens 2

Hi! I am currently using Hololens 2 and Unity to develop MR-related work. I intend to use "Holographic Emulation" in Unity to run the program directly in Unity Editor(Ref: Unity Play Mode with Holographic Remoting, https://learn.microsoft.com/en-us/windows/mixed-reality/develop/unity/unity-play-mode). However, the connection always fails with these two errors: "TransportConnectionFailed" and "TransportPortBusy". My Unity version is 2019.4.9f1, but I have tried some old versions, e.g. 2019.1, 2019.3 with the same errors.

I followed the instructions and used the Holographic(Deprecated) in Unity. Also, I have tried new XR plugins Management in Unity, but it also failed. I am considering the version compatibility of Unity and Hololens 2 SDK. So, it would be really appreciated if more information or instructions could be shared to get the "Connection Status" Connected.

Thank you in advance!

Besides, I am not sure if the "tag" of this question is correct. If not, please inform me of the right one. Thanks!

Best regards!
