Steps to reproduce

Clone this demo project and launch the project.

https://github.com/nayooti/GoogleMapsDemo

In MapController.swift set GoogleMaps API Key.

let apiKey = "YOUR_API_KEY"

Start the app preferably on a real device (the app caused my machine to crash).

You will see The app “App” has been killed by the operating system because it is using too much memory.

   public override func viewDidAppear(_ animated: Bool) {
       super.viewDidAppear(animated)
       // crashes app
       // mapView.drawLine(from: berlin, to: munich, navigationType: .car)

       // does not crash app
       mapView.drawLine(from: berlin, to: potsdam)
   }

Now: in MapController in viewDidAppear draw a shorter polyline (20km) The app won't crash.

The code used to work in previous GoogleMaps versions.

    fetchPolylineWithOrigin(
            start: CLLocation(latitude: from.coordinates.latitude, longitude: from.coordinates.longitude),
            dest: CLLocation(latitude: to.coordinates.latitude, longitude: to.coordinates.longitude),
            navigationType: navigationType
        ) { [weak self] polyline in

            guard let self = self else { return }

            let styles = [
                GMSStrokeStyle.solidColor(.systemBlue),
                GMSStrokeStyle.solidColor(.clear)
            ]

            polyline.strokeWidth = 6
            let lengths = [3, 2]

            polyline.spans = GMSStyleSpans(polyline.path!, styles, lengths as [NSNumber], GMSLengthKind.rhumb)
            // here the crash is happening
            polyline.map = self
        }
The crash happems when the map is assigned to GMSPolyline.
