Text Gets Cut Off in Android DialogFragment

The bottom half of the text contained in my DialogFragment is getting cut off. This is what it looks like:

Does anyone know what I am doing wrong, and how to fix it? Below is my current setup:

MainFragment.kt

class MainFragment(private val screenField: String): DialogFragment() {

    private lateinit var mBinding: FragmentMainBinding

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        mBinding = FragmentMainBinding.inflate(LayoutInflater.from(context))
        mBinding.screenField.text = screenField
  
        return AlertDialog.Builder(context!!)
            .setView(mBinding.root)
            .setPositiveButton(R.string.ok, null)
            .create()
    }

    override fun onStart() {
        super.onStart()
        val width = resources.getDimensionPixelSize(400dp)
        val height = resources.getDimensionPixelSize(150dp)
        dialog?.window?.setLayout(width, height)
    }

}

fragment_main.xml

    <TextView

        android:layout_height="wrap_content"
        android:textSize="40sp"
        android:textColor="@android:color/black"/>
