Problems when connecting unity and HoleLens.

Question

I'm using unity 2021.3.34f1 to edit a scene that needs to run on hololens2, but I'm having the following problems:

1. In the build setting interface, there is no "target device" field where I can select the "Hololens" option.
2. When trying to connect , after pressing play game, the Unity scene does not appear in Hololens. (In the unity side of the Holographic Remotion for Play mode interface, I entered the server IP of Hololens, and the button switched to the state of "disable Holographic Remotion for Play mode", which means that the computer side is ready; the Hololens side is also ready; the Hololens side is also ready; The Hololens side also shows the ready screen.
3. When I try to connect, the MRTK Project Configurator pops up, but I don't know what else I haven't set up. (I have checked the box: "Holographic Remoting remote APP" "Microsoft HoloLens" I have these options checked.) Translated with www.DeepL.com/Translator (free version)

Hello, Welcome to Microsoft Q&A,

In the new version, the ‘Target Device’ has been removed. You can configure the building settings as shown in the following image:
