ios 15.01 after capturing AR content in QLPreviewController the background is black, only 3D model is visible

In preview, the 3D model is visible in the background but once the camera button is pressed the image in the screenshot is just the 3D model with a black background which is also saved. QLPreviewController implementation:

`func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        thumbnailIndex = indexPath.item
        
        let previewController = QLPreviewController()
        previewController.dataSource = self
        previewController.delegate = self
        present(previewController, animated: true)
    }
    
    func numberOfPreviewItems(in controller: QLPreviewController) -> Int {
        return 1
    }
    
    func previewController(_ controller: QLPreviewController, previewItemAt index: Int) -> QLPreviewItem {
        let url = Bundle.main.url(forResource: models[thumbnailIndex], withExtension: "usdz")!
        return url as QLPreviewItem
    }`

console output is:
