Kotlin 1.1.3-2 No se puede crear una instancia de fragment en OnResume Android

Tengo este problema aquí:

FATAL EXCEPTION: main Process: com.mytest.app, PID: 20586 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mytest.app/com.mytest.app.activities.home.HomeActivity}: android.app.Fragment$InstantiationException: Unable to instantiate fragment com.mytest.app.activities.fragments.MyFragment: make sure class name exists, is public, and has an empty constructor that is public at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2371) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2423) at android.app.ActivityThread.access$800(ActivityThread.java:151) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1342) at android.os.Handler.dispatchMessage(Handler.java:110) at android.os.Looper.loop(Looper.java:193) at android.app.ActivityThread.main(ActivityThread.java:5327) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:824) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:640) at dalvik.system.NativeStart.main(Native Method) Caused by: android.app.Fragment$InstantiationException: Unable to instantiate fragment com.mytest.app.activities.fragments.MyFragment: make sure class name exists, is public, and has an empty constructor that is public at android.app.Fragment.instantiate(Fragment.java:605) at android.app.FragmentState.instantiate(Fragment.java:98) at android.app.FragmentManagerImpl.restreAllState(FragmentManager.java:1759) at android.app.Activity.onCreate(Activity.java:903) at android.support.v4.app.FragmentActivity.onCreate(FragmentActivity.java:277) at android.support.v7.app.AppCompatActivity.onCreate(AppCompatActivity.java:84) at com.mytest.app.activities.MyActivity.onCreate(MyActivity.java:26) at com.mytest.app.activities.home.HomeActivity.onCreate(HomeActivity.kt:83) at android.app.Activity.performCreate(Activity.java:5343) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1088) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2331) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2423) at android.app.ActivityThread.access$800(ActivityThread.java:151) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1342) at android.os.Handler.dispatchMessage(Handler.java:110) at android.os.Looper.loop(Looper.java:193) at android.app.ActivityThread.main(ActivityThread.java:5327) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:824) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:640) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.IllegalAccessException: access to constructor not allowed at java.lang.Class.newInstanceImpl(Native Method) at java.lang.Class.newInstance(Class.java:1215) at android.app.Fragment.instantiate(Fragment.java:590) at android.app.FragmentState.instantiate(Fragment.java:98) at android.app.FragmentManagerImpl.restreAllState(FragmentManager.java:1759) 

Traté de cambiar mi Objeto Kotlin a class utilizando CompanionObject con un constructor estático, pero tengo el mismo resultado.

El problema se aleatoriza cuando estamos en otra aplicación y queremos volver a nuestra aplicación.

¿Alguna ayuda?

Gracias.

—— EDIT —— Aquí está mi código de object kotlin:

 object MyFragment : Fragment() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) } override fun onResume() { super.onResume() } override fun onDestroy() { super.onDestroy() } override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? { return inflater.inflate(R.layout.fragment_myfragment, container, false) } override fun onViewCreated(view: View?, savedInstanceState: Bundle?) { super.onViewCreated(view, savedInstanceState) } override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) { inflater.inflate(R.menu.mymenu, menu) } override fun onOptionsItemSelected(item: MenuItem): Boolean { // handle item selection when (item.itemId) { R.id.action_my_results -> { return true } else -> return super.onOptionsItemSelected(item) } } override fun onAttach(context: Context) { super.onAttach(context) } override fun onDetach() { super.onDetach() }}
