override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    arguments?.let {
        param1 = it.getString(ARG_PARAM1)
        param2 = it.getString(ARG_PARAM2)
    }
}

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    // Inflate the layout for this fragment
    val xml= inflater.inflate(R.layout.fragment_listfragment, container, false)
    val list=ArrayList<shopinglist>()
    viewmodel= ViewModelProvider(this).get(Listviewmodel::class.java)
                         error is here 


    xml.recyclerView.layoutManager= LinearLayoutManager(context, RecyclerView.VERTICAL,false)
        xml.recyclerView.adapter=Customadapterforrecyle(this,list)

    }
    fun delete(item:shopinglist)=CoroutineScope(Dispatchers.IO).launch {

Make sure You have the appropriate Fragment imported. You might have the one from the android.app package:

import android.app.Fragment;

This one does not implement the ViewModelStoreOwner interface. On the other hand the Fragment from the androidx.fragment.app package does. Replace the previous import with this one:

import androidx.fragment.app.Fragment;
