Just remove android:name tag from <fragment .../>..

And use FrameLayout instead of fragment.

Or you can use below code.

<FrameLayout
        android:layout_width="362dp"
        android:layout_height="98dp"
        android:id="@+id/sigup_fragment"
        android:layout_marginEnd="8dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="16dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="@+id/guideline"
        app:layout_constraintTop_toBottomOf="@+id/mood_tv" />

It also gives an exception on SIgnup.kt that `must implement OnFragmentInteractionListener` – SFAH Oct 08 '19 at 11:23
I have seen you code.. OnFragmentInteractionListener is not needed as I understand, so you can remove all things related to that listener. – DHAVAL A. Oct 08 '19 at 11:25

Problem is here com.example.pickingredients.ImagesliderFragment. Either this fragment not found or having issues on that fragment.

And you should use FrameLayout instead of Fragment in xml.

Moreover your MainActivity should implement OnFragmentInteractionListener
