When streaming through SteamVR and PICO headsets, the project launching the OpenXR plugin may get stuck

UE5.1.1，SteamVR2.1.10，Windows10，My HMD is Pico4Pro. I set the OpenXR runtime to SteamVR in the SteamVR application.
When I successfully stream the PICO headset device using the SteamVR application, I get stuck at 35% progress when launching a project that includes the OpenXR plugin, even if I try to use the official VR template. When I closed the OpenXR plugin, the project successfully started.I have tried it on three computers and it’s all like this. A month or two ago, the VR preview was good. I don’t know what happened to OpenXR and SteamVR.
But I need the OpenXR plugin to implement VR preview. I converted the VR template blueprint project into a C++ project, and then launched the project in Visual Studio. The first image is the output log when the project starts without opening the OpenXR plugin, and the second image is the output log when the project gets stuck after opening OpenXR. Can anyone solve this problem?

Through continuous attempts, I have found a solution that is available for testing in UE5.03 and 5.11 versions.

1. Open the VR project, open SteamVR in the plugin, close OpenXR, and restart the project

2. After restarting the project, Steam and SteamVR will be automatically opened. Don’t worry about the SteamVR display not detecting the head display device, do not close the project and SteamVR

3. PC and PICO open the streaming assistant for streaming, and the PC will automatically restart SteamVR to find the head display device, displaying normal streaming

4. After restarting the project again, VR preview will be available
