Android - Call notifyDataSetChanged() on recycler view ListAdapter

I have a recycler view ListAdapter (coming from androidx)

I know that one is not supposed to use notifyDataSetChanged() any more with a ListAdaper but I am in a situation where it's necessary (onBindViewHolder() should be invoked without changing the submitlist)

The problem is that I have a compilation error when I call notifyDataSetChanged() like this:

binding.episodesRv.adapter.notifyDataSetChanged()

Compilation error:

Smart cast to '({Adapter<(androidx.recyclerview.widget.RecyclerView.ViewHolder..
androidx.recyclerview.widget.RecyclerView.ViewHolder?)> & EpisodeListAdapter}..
EpisodeListAdapter)' is impossible, because 'bd.episodesRv.adapter' is a complex expression

The adapter :

class EpisodeListAdapter(
    val context: Context,
    var epiId: StateFlow<Long>,
    val selectEpisode: (episode: Episode) -> Unit,
    val delete: (episode: Episode) -> Unit,
) : ListAdapter<Episode, EpisodeViewHolder>(EPISODE_COMPARATOR) {
 ....
