я получаю следующее падение при использовании быстрого адаптера

и иногда это крушение

вот мой код 

class ListingAttributes(private val activity: ListingDetailsActivity, private val viewModel: ListingAttributesViewModel) : AbstractItem<ListingAttributes, ListingAttributes.ViewHolder>() {

    override fun getLayoutRes() = R.layout.recycler_view_listing_attributes_item
    override fun getType() = R.id.recycler_view_listing_attributes_item

    override fun getViewHolder(v: View) = ListingAttributes.ViewHolder(
            RecyclerViewListingAttributesItemBinding.bind(v), activity, viewModel)

    class ViewHolder(private val binding: RecyclerViewListingAttributesItemBinding, private val activity: ListingDetailsActivity, private val viewModel: ListingAttributesViewModel) :
            FastAdapter.ViewHolder<ListingAttributes>(binding.root) {

        private var itemAdapter = ItemAdapter<IItem<*, *>>()

        private val loadAttributesFromDBObserver = Observer<Unit> {

            //binding.recyclerView.addView(AttributeBoolViewGrid(activity, viewModel.attributes.filter { it.type == AttributeType.BOOL.value }))

            viewModel.attributes.forEach { item ->
                when (item.type) {

                    AttributeType.TEXT.value, AttributeType.NUMBER.value, AttributeType.DROP_DOWN.value -> {
                        val listAttr = viewModel.listingAttribute.find { it.id.toInt() == item.id }
                        listAttr?.let { AttributeView(activity, listAttr, item, AttributeViewViewModel(viewModel.optionDao)).also { item -> itemAdapter.add(item) } }
                    }
                }
            }



            itemAdapter?.let {

                val fastAdapter: FastAdapter<IItem<*, *>> = FastAdapter.with(
                    listOf(
                        itemAdapter
                    )
                )

                fastAdapter.apply {
                    setHasStableIds(true)
                    withSelectable(true)
                }

                binding.recyclerView.apply {

                    layoutManager = LinearLayoutManager(context)
                    adapter = fastAdapter
                }

            }
        }

        override fun bindView(item: ListingAttributes, payloads: MutableList<Any>) {

            viewModel.loadAttributesFromDBEvent?.observe(activity, loadAttributesFromDBObserver)
        }

        override fun unbindView(item: ListingAttributes) {

            viewModel.loadAttributesFromDBEvent.removeObservers(activity)
        }
    }
}

а это моя модель взгляда 

class ListingAttributesViewModel(val activity: Activity, val listingAttribute: List<ListingExtraAttr>) : BaseStatefulViewModel() {

    private val extraAttributesRepository: ExtraAttributeRawRepository by inject()
    val optionDao: ExtraAttributeOptionDao by inject()
    lateinit var attributes: List<ExtraAttributeEntity>
    val loadAttributesFromDBEvent = LiveEvent<Unit>()

    init {
        getAttributes(listingAttribute.joinToString { it.id })
    }

    private fun getAttributes(attributesIds: String) {

        launch(Dispatchers.IO) {
            extraAttributesRepository?.let {
                attributes = extraAttributesRepository.getExtraAttributesByIds(attributesIds)
                loadAttributesFromDBEvent.call()
            }
        }
    }
}

Может кто-нибудь помочь, пожалуйста, авария не говорит никакой информации о том, где это произошло?
