This problem in the CameraEngine handleDeviceOrientation. I changed this functions and solved this problem

  private func handleDeviceOrientation() {
        if self.rotationCamera {
			if (!UIDevice.current.isGeneratingDeviceOrientationNotifications) {
				UIDevice.current.beginGeneratingDeviceOrientationNotifications()
			}
            NotificationCenter.default.addObserver(forName: NSNotification.Name.UIDeviceOrientationDidChange, object: nil, queue: OperationQueue.main) { [weak self] (_) -> Void in
                guard self != nil else { return }
                if self!.rotationCamera {
                    
                    let orientation = AVCaptureVideoOrientation.orientationFromUIDeviceOrientation(UIDevice.current.orientation)

                    if orientation == .portraitUpsideDown {
                        return
                    }
                    
                    self!.previewLayer.connection?.videoOrientation = AVCaptureVideoOrientation.orientationFromUIDeviceOrientation(UIDevice.current.orientation)
                }
            }
        }
        else {
			if (UIDevice.current.isGeneratingDeviceOrientationNotifications) {
				UIDevice.current.endGeneratingDeviceOrientationNotifications()
			}
            NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIDeviceOrientationDidChange, object: nil)
        }
    }
