App keeps crashing when I click on a crime

Pretty much what it says on the tin, I was making the changes seen on pg. 222 when for some reason the app stops working as intended. It will open when I start running it, but the moment I click on a crime the app crashed. I tried looking through logcat but cannot find the problem spot, instead taking me to CrimeDao even though it was working fine until I got the changes in pg.222.

My code:

class CrimeDetailFragment : Fragment() {
private val args: CrimeDetailFragmentArgs by navArgs()
private lateinit var binding: FragmentCrimeDetailBinding

private val crimeDetailViewModel: CrimeDetailViewModel by viewModels{
    CrimeDetailViewModelFactory(args.crimeId)
}

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    binding =
        FragmentCrimeDetailBinding.inflate(layoutInflater, container, false)
    return binding.root
}

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    binding.apply {
        crimeTitle.doOnTextChanged{
            text,_,_,_->
        }
        crimeDate.apply {
            isEnabled = false
        }

        crimeSolved.setOnCheckedChangeListener{
            _, isChecked ->
        }
    }

    viewLifecycleOwner.lifecycleScope.launch {
        viewLifecycleOwner.lifecycle.repeatOnLifecycle(Lifecycle.State.STARTED){
            crimeDetailViewModel.crime.collect{ crime -> crime?.let { updateUi(it) }}
        }
    }
}

override fun onDestroyView() {
    super.onDestroyView()
    _binding = null
}

private fun updateUi(crime: Crime){
    binding.apply {
        if (crimeTitle.text.toString() != crime.title){
            crimeTitle.setText(crime.title)
        }
        crimeDate.text = crime.date.toString()
        crimeSolved.isChecked = crime.isSolved
    }
}

}

Hmm that is strange. At this point in the chapter, clicking an individual item in the list should still do the same thing as what you coded up all the way back in chapter 10, which is show a toast. Can you also share the code for CrimeListFragment.kt and nav_graph.xml?
