ARKit 人物遮挡 (.personSegmentationWithDepth) 冻结相机 (ARSceneView)

Question

当我在 ARKit 中切换到 People Occlusion (.personSegmentationWithDepth) 时，ARSCNView 有时会冻结。 下面的代码在 iOS 14.1 之前对我来说很好用。或者。现在，当切换到 .personSegmentationWithDepth 时，相机不会冻结，这只是幸运

func setupScene() {
    sceneView.delegate = self
    sceneView.session.delegate = self
    sceneView.autoenablesDefaultLighting = true
    sceneView.scene = scene
  }

  func initSceneSession() {
    let configuration = ARWorldTrackingConfiguration()
    configuration.planeDetection = .horizontal
    sceneView.session.run(configuration, options: [.resetTracking, .removeExistingAnchors])
  }

 func switchPeopleOcc(on: Bool){
    guard let config = sceneView.session.configuration as? ARWorldTrackingConfiguration,
      ARWorldTrackingConfiguration.supportsFrameSemantics(.personSegmentationWithDepth) else {            return
    }
    
    switch on {
    case true:
      config.frameSemantics.insert(.personSegmentationWithDepth)
    case false:
      config.frameSemantics.remove(.personSegmentationWithDepth)
    }
    
    sceneView.session.run(config)
  }
