Using Laptop Integrated Camera in Unity Project

Hello everyone,

I am trying to let the Vuforia ARCamera to use the laptop's integrated camera in a Unity project. Inside the Unity editor, I can play the scene showing the camera image with no problem. However, when I build and run project, a black screen will be displayed and an error saying "Failed to start Vuforia"  can be seen in the debug build.

The problem disappear when I am working with an external USB camera. I learned that Vuforia has removed the support for the front camera and this seems to cause my issue, but due to the project's requirement, I still need to use the the laptop's integrated camera. I tried a many methods but still not able to get the integrated camera work in a built version. Has anyone been able to solve this issue? Thanks in advance!

Below is more detailed information:

I am testing with the ModelTargetStandard scene in the Vuforia Core Samples in the following environment:

• OS: Windows10
• Vuforia: 10.10.2
• Unity: 2021.3.10f1
• Project platform: UWP

The detail build setting can be found below.

What I see in the Unity editor

and what I see in the build version is like

In the bottom-left corner, the message of the "Failed to start Vuforia" error is displayed.

I tried the following methods but ended up in failure:

1. Add an entry in the webcamprofiles.xml with name 'Integrated Webcam', same as the device name provided by Unity.
2. In the c# script, set VuforiaConfiguration.Instance.WebCam.DeviceNameSetInEditor = "Integrated Webcam".
3. In the c# script, set webcamTexture.deviceName = devices[0].name.
4. Rename the integrated camera to 'HD Web Camera' in windows registry editor.

I will really appreciate it if you could help me look into this problem!
