You need to make standardBottomSheetBehavior nullable then in FragmentTripPlanner.onDestroyView(), you need to clear the reference to standardBottomSheetBehavior since it has a reference to standardBottomSheet

    override fun onDestroyView() {
        super.onDestroyView()
        binding=null
        standardBottomSheetBehavior = null
    }
