Kotlin 1.4.10 and ClassCastException while using coroutines

After upgrade to Kotlin 1.4.10, my Android application started to throw exceptions while using coroutines. My code:

class CollectionBookRepositoryImpl @Inject constructor(
    @CollectionBookReference private val reference: DatabaseReference,
) : CollectionBookRepository {

    override suspend fun add(book: CollectionBook): Result<Unit> {
        return runCatching {
            reference.setValue(book).await()
        }
    }
}

class AddCollectionBookUseCaseImpl @Inject constructor(
    private val collectionBookRepository: CollectionBookRepository,
) : AddCollectionBookUseCase {

    override suspend fun invoke(input: CollectionBook): Result<Unit> =
        collectionBookRepository.add(input)
}

class BookEditViewModel @Inject constructor(
    private val addCollectionBook: AddCollectionBookUseCase,
) : BaseViewModel() {

    fun addBook() {
        val book = CollectionBook()

        viewModelScope.launch(Dispatchers.IO) {
            val result = addCollectionBook(book)
            if (result.isSuccess) {
                _state.postValue(BookEditState.BookAdded)
            } else {
                val errorState = BookEditState.Error(R.string.adding_book_error_message)
                _state.postValue(errorState)
            }
        }
    }
}

Invoking addBook() method in ViewModel causes application crash. Stacktrace of exception:

Moreover, when I change addBook() method to:

fun addBook() {
    val book = CollectionBook()

    addCollectionBook(book)
        .onSuccess {
            _state.postValue(BookEditState.BookAdded)
        }
        .onFailure {
            val errorState = BookEditState.Error(R.string.adding_book_error_message)
            _state.postValue(errorState)
        }
}

it throws:

Is it even possible to fix without any update from Kotlin authors?
