Vuforia 10.13 with Unity 2021 on M2 Macbook - Failed to get WebCam Image

Hello,

I updated a Unity project to Unity 2021.3.18 and also updated Vuforia to the latest version (10.13).

When starting my app in editor and going into an AR scene, I get an error "Failed to get WebCam Image!" and the webcam does not start. This error also sometimes comes some seconds after starting my app (no AR scene at this point).

I am on a Macbook Pro 2023 with M2 Max chip.

My app starts with non-AR scenes and I load my AR scenes with a loading-screen scene in the background.

I created a completely independent AR scene in the same project and started it in playmode and my camera works. so it does not seem to be a general issue.

Any idea what I could do? Is there some sort of re-initialization of the ARCamera once my AR scene started to get the macbook internal camera to work?

By the way, when I build the project to iOS on a real device, the AR works fine. It's just not working in editor.

Also I tried loading my scene directly with an OnGUI button with the SceneManager without any loading scene and it did also not work. so I guess thats also not the issue.

Hope anyone has an idea :(

Cheers, Robert
