crash while .startNavigation been called

My application crash when I try to use the navigation function while my network connection is on data(4G), when the connection is wifi, the navigation is working.

using android 8.0, kotliin and com.mapbox.navigation:ui:1.1.0

Code:
override fun onRoutesReady(routes: List) {
if (routes.isNullOrEmpty()) {
handleRouteError()
return
}
val optionsBuilder = NavigationViewOptions.builder(requireContext())
optionsBuilder.camera(SimpleCamera())
optionsBuilder.arrivalObserver(this)
optionsBuilder.shouldSimulateRoute(true)
optionsBuilder.directionsRoute(routes[0])
val options = optionsBuilder.build()
navigationView.startNavigation(options)

}

Crash :

Inizia esaminando NavigationView.startNavigation e NavigationViewModel.initializeDistanceFormatter e buildDistanceFormatter indicati nello stack trace nella versione 1.1.0. Riproduci il crash su Android 8.0 con una connessione 4G, quindi confrontalo con il Wi-Fi e con il flusso onRoutesReady fornito. Il lavoro è completo quando startNavigation non genera più l'eccezione relativa al parametro null segnalata nello scenario interessato.
