I using navigation graph and I use 

val action = MainFragmentDirections.actionMainToPaymentFragment(viewModel.paymentDetails!!)
binding.PayBills.findNavController().navigate(action)

To navigate, my problem was is that whenever I change the app to landscape from portrait and from portrait to landscape it crashes on navigation, I made the application portrait only and it worked but now I am having problem with foldable devices
