Hi @sheinin Sorry for the late reply. This looks like a duplicate of https://github.com/realm/realm-kotlin/issues/339#issuecomment-893277100 . Unfortunately it is an issue with the Kotlin Compiler and how it handles inner classes and generics.

Can you try to move your ViewHolder outside the CustomAdapter so:

class ViewHolder { } 
class CustomAdapter(private val mList: List<ItemsViewModel>) : RecyclerView.Adapter<ViewHolder>() {...}

It’s working, sorry took long to test. Many thanks!
