SwiftUI AVCaptureSession 冻结 VStack 或 ScrollView 中的其他视图

Question

我有一个视图，其中包含滚动视图中的一些文本、按钮和相机视图

         VStack {
            ZStack{
                ScrollView{
                    
                    HStack(alignment: .top) {
                        LogoMainView()
                    }
                    .frame(maxWidth: .infinity, maxHeight: 44, alignment: .leading)
                    .padding(.horizontal,5)
                    VStack{
                        HeaderText(title:"Some header")
                        ParagraphText(text:"Some random text")
                        CameraDropDown(
                            toggleFront:{
                                self.captureSession.changeOrientation(orientation: .front)
                            },toggleBack: {
                                self.captureSession.changeOrientation(orientation: .back)
                            })
                      CameraView()
                        .onAppear(){
                        self.appDelegate.captureSession.setup()
                        self.appDelegate.captureSession.start()
                        }
                       .onDisappear(){
                          self.appDelegate.captureSession.stop()
                        }
                       .onChange(of: self.appDelegate.captureSession.orientation){
                         newvalue in
                         self.appDelegate.captureSession.orientation = newvalue
                         self.appDelegate.captureSession.setup()
                         self.appDelegate.captureSession.start()
                        }
                        
                    }
                    .padding(.horizontal,10)
                }
            }
        }
        .clipped()
       }

每当相机开始单击 CameraDropDown 时，它应该改变方向但扩展然后选择所需的方向但是当 CameraView() 正在运行时，即（相机正在显示）它只是不响应触摸但是当我切换 CameraView()它响应触摸和方向的变化。

我尝试的是分析挂起，但我无法挂起。

这是我的相机课

            return

        session.addInput(videoDeviceInput)
        session.commitConfiguration()
        
        let videoOutput = AVCaptureVideoDataOutput()
        videoOutput.setSampleBufferDelegate(self, queue: DispatchQueue(label: "SampleBuffer"))
        if (session.canAddOutput(videoOutput)) {
            session.addOutput(videoOutput)

                    self.setup()
                    self.start()
                }
            }
            
        }
}

extension CaptureSession: AVCaptureVideoDataOutputSampleBufferDelegate {
    func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) {
        DispatchQueue.main.async {
            self.sampleBuffer = sampleBuffer
        }
    }
}

如何使相机运行并响应我拥有的其他视图的触摸或我在这里做错了什么？ 请帮忙。
