Unity Play Mode with Holographic Remoting---Failed to enable remoting runtime

Question

I want to use Holographic Remoting to stream holographic content to HoloLens 2 in real time. I follow this tutorial to preview my work with Holographic Remoting. But when I click the 'play' button in unity, I get this error in unity

Failed to enable remoting runtime.
UnityEngine.Debug:LogError (object)
Microsoft.MixedReality.OpenXR.Remoting.PlayModeRemotingPlugin:HookGetInstanceProcAddr (intptr) (at Library/PackageCache/com.microsoft.mixedreality.openxr@a4cc3ecd3f67/Runtime/FeaturePlugins/PlayModeRemotingPlugin.cs:77)
UnityEngine.XR.Management.XRGeneralSettings:AttemptInitializeXRSDKOnLoad () (at Library/PackageCache/[email protected]/Runtime/XRGeneralSettings.cs:148)

The Holographic Remoting App in Hololens2 had no response.
This figure shows my setting and versions of unity, openXR plugin, Mixed Reality OpenXR Plugin. How can I solve it? Thanks!

The figure about "XR Plug-in Management" and "OpenXR"

We can pass data to another activity using Intent.

Like before startActivity we need to do: intent.putExtra("Data", data);

and in thirdActivity onCreate we need to do intent.getStringExtra("Data");
