Unity debugging VR applications fails to start.

I'm a Quest3 application developer on Unity. I'm developing my application using Unity. I streamed my Quest to the computer using Meta Horizon Link + streaming cable, and then clicked "Run with Unity" to start my project. At this point, Quest didn't succeed, but I could still see the Unity editor. Theoretically, it should have entered my VR application, but it seems that it didn't start successfully.

However, when I unchecked the Meta XR Feature in open xr setting, Unity Editor run this application normally, but all the Meta XR functions were lost. The screen moves along with my head (head tracking fails), and it cannot detect any controllers or gestures. The software version of my Quest 3 is v0.83. The version of Meta Horizo n Link is 0.83/0.85 (both versions have been tested and the phenomenon is the same), and the version of Meta XR SDK has also been tested (0.83, 0.77, 0.76, 0.74). What caused this?

I used the official sample scenario. I repeatedly checked all the configurations of Unity and everything was normal. Moreover, when I packaged and built it to run on the all-in-one machine, it also ran normally

I was running the simplest scenario with only a camera. I also tried the sample scenario provided by the Meta XR SDK, and the phenomenon was the same
