When you are calling super.onCreate(savedInstanceState) in your HomeActivity, the onCreate from android's Activity is called, but not the onCreate from BaseActivity - because it expected second param persistentState.

So you can do this options to fix the issue:

1. call super method with 2 params in your HomeActivity

    class HomeActivity ... {
   ...
       override fun onCreate(savedInstanceState: Bundle?, persistentState: PersistableBundle?) {
           super.onCreate(savedInstanceState, persistentState) 
           dataBinding.vm = viewModel
       } 

OR

1. use onCreate with one param in your BaseActivity

    open abstract class BaseActivity<T : ViewDataBinding , VM : ViewModel> : AppCompatActivity() {
   
       lateinit var dataBinding : T
       lateinit var viewModel : VM
   
       override fun onCreate(savedInstanceState: Bundle?) {
           super.onCreate(savedInstanceState)
          ...
