merge room with WorldMap

I'm trying to merge room with WorldMap: but my screen goes black when doing a scan, First: i load world map

                arWorldTrackingConfig.initialWorldMap = worldMap
                //arWorldTrackingConfig.planeDetection = [.horizontal, .vertical]
                arSession.run(arWorldTrackingConfig)
                if #available(iOS 17.0, *) {
                    roomCaptureView = RoomCaptureView(frame: view.bounds, arSession: arSession)
                }
                else{
                    roomCaptureView = RoomCaptureView(frame: view.bounds)
                }
        roomCaptureView = RoomCaptureView(frame: view.bounds)
        roomCaptureView.captureSession.delegate = self
        roomCaptureView.delegate = self
        view.insertSubview(roomCaptureView, at: 0)

and save when scan done:

roomCaptureView?.captureSession.arSession.getCurrentWorldMap { worldMapData, error in
            if let error = error {
                return
            }
            if let worldMap = worldMapData {
                
                let fileURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0].appendingPathComponent("worldMapData")
                do {
                    let data = try NSKeyedArchiver.archivedData(withRootObject: worldMap, requiringSecureCoding: true)
                    try data.write(to: fileURL)

                } catch {
                    print("error ARWorldMap: \(error.localizedDescription)")
                }
            }
            
        }
 

the first scan is fine, but the next time, when the worldMap is saved and loaded, my screen goes black, does anyone have a solution or sample code?? -thank-
