Crashes on startup without logcat at 6.13

Android Programming (4th Edition) 6. Your Second Activity
1

Just as the title says, it crashes on startup without a LOGCAT output and no errors at around 6.13
Here’s my MainActivity

package com.jacobjumper.geoquiz

import android.content.Intent
import android.os.Bundle
import android.os.PersistableBundle
import android.view.View
import android.widget.Button
import android.widget.TextView
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import androidx.lifecycle.ViewModelProvider

private const val KEY_INDEX = "index"

class MainActivity : AppCompatActivity() {

    private lateinit var trueButton: Button
    private lateinit var falseButton: Button
    private lateinit var nextButton: Button
    private lateinit var prevButton: Button
    private lateinit var cheatButton: Button
    private lateinit var questionTextView: TextView
    private lateinit var quizViewModel: QuizViewModel

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        savedInstanceState?.putInt(KEY_INDEX, quizViewModel.currentIndex)
        setContentView(R.layout.activity_main)
        quizViewModel = ViewModelProvider(this)[QuizViewModel::class.java]

        trueButton = findViewById(R.id.true_button)
        falseButton = findViewById(R.id.false_button)
        cheatButton = findViewById(R.id.cheat_button)
        nextButton = findViewById(R.id.next_button)
        prevButton = findViewById(R.id.back_button)
        questionTextView = findViewById(R.id.question_text)


        trueButton.setOnClickListener {
            checkAnswer(true)
        }

        falseButton.setOnClickListener {
            checkAnswer(false)
        }

        nextButton.setOnClickListener {
            quizViewModel.moveToNext()
            updateQuestion()
        }

        prevButton.setOnClickListener {
            quizViewModel.moveToBack()
            updateQuestion()
        }

        cheatButton.setOnClickListener {
            // Start intent
            val answerIsTrue = quizViewModel.currentQuestionAnswer
            val intent = CheatActivity.newIntent(this@MainActivity, answerIsTrue)
            startActivity(intent)
        }

        updateQuestion()
    }

    private fun checkAnswer(userAnswer: Boolean){
        val correctAnswer = quizViewModel.currentQuestionAnswer
        val messageResId = if (userAnswer == correctAnswer) {
            R.string.correct_toast
        } else {
            R.string.incorrect_toast
        }
        Toast.makeText(
            this,
            messageResId,
            Toast.LENGTH_SHORT
        ).show()
    }

    private fun updateQuestion() {
        val questionTextResID = quizViewModel.currentQuestionText
        questionTextView.setText(questionTextResID)
    }


}

and here’s my CheatActivity

package com.jacobjumper.geoquiz

import android.content.Context
import android.content.Intent
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.Button
import android.widget.TextView
import org.w3c.dom.Text
import java.security.AccessControlContext

private const val EXTRA_ANSWER_IS_TRUE =
        "com.jacobjumper.geoquiz.answer_is_true"

class CheatActivity : AppCompatActivity() {

    private lateinit var answerTextView: TextView
    private lateinit var showAnswerButton: Button

    private var answerIsTrue = false

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_cheat)

        answerIsTrue = intent.getBooleanExtra(EXTRA_ANSWER_IS_TRUE, false)
        answerTextView = findViewById(R.id.answer_text_view)
        showAnswerButton = findViewById(R.id.answer_button)
        showAnswerButton.setOnClickListener {
            val answerText = when {
                answerIsTrue -> R.string.true_button
                else -> R.string.false_button
            }
            answerTextView.setText(answerText)
        }
    }

    companion object {
        fun newIntent(packageContext: Context, answerIsTrue: Boolean): Intent {
            return Intent(packageContext, CheatActivity::class.java).apply {
                putExtra(EXTRA_ANSWER_IS_TRUE, answerIsTrue)
            }
        }

    }
}

This is an older book so I’m willing to bet something is depreciated somewhere. Please assist. Thank you.
