初始化 MvpAppCompatFragment 片段时 Moxy 崩溃

尝试掌握 Moxy 2.1.2

因错误而崩溃：

我知道问题出在片段中

import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import moxy.MvpAppCompatFragment
import moxy.ktx.moxyPresenter
import ru.example.stat.R
import ru.example.stat.presenters.EventPresenter
import ru.example.stat.views.EventView


class EventFragment : MvpAppCompatFragment(R.layout.fragment_events), EventView{

    private val eventPresenter by moxyPresenter { EventPresenter() }


    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? =
        inflater.inflate(R.layout.fragment_events, container, false)
}

我做错了什么，可能是什么问题？

在 MainActivity onCreate：

 override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    val navView: BottomNavigationView = findViewById(R.id.nav_view)


    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED)
    navView.setOnNavigationItemSelectedListener(onNavigationItemSelectedListener)
    val fragment = EventFragment()
    addFragment(fragment)
}

private fun addFragment(fragment: Fragment){
    supportFragmentManager.beginTransaction().replace(R.id.container, fragment, fragment.javaClass.getSimpleName())
        .commit()
}
