Pink Screen with VideoMaterial in ARKit

Hi everyone,

I'm developing an ARKit app using RealityKit and encountering an issue where a video displayed on a 3D plane shows up as a pink screen instead of the actual video content.

Here's a simplified version of my setup:

func createVideoScreen(video: AVPlayerItem, canvasWidth: Float, canvasHeight: Float, aspectRatio: Float, fitsWidth: Bool = true) -> ModelEntity {
    let width = (fitsWidth) ? canvasWidth : canvasHeight * aspectRatio
    let height = (fitsWidth) ? canvasWidth * (1/aspectRatio) : canvasHeight
    let screenPlane = MeshResource.generatePlane(width: width, depth: height)

    let videoMaterial: Material = createVideoMaterial(videoItem: video)
    let videoScreenModel = ModelEntity(mesh: screenPlane, materials: [videoMaterial])
    return videoScreenModel
}

func createVideoMaterial(videoItem: AVPlayerItem) -> VideoMaterial {
    let player = AVPlayer(playerItem: videoItem)
    let videoMaterial = VideoMaterial(avPlayer: player)
    player.play()
    return videoMaterial
}

Despite following the standard process, the video plane renders pink. Has anyone encountered this before, or does anyone know what might be causing it?

Thanks in advance!
