Room (266) statement aborts disk I/O error

After i insert fastly X records in my database the app at certain point crash with the following stack trace:

Actually i call the DAO method which calls the query which is in the stacktrace is in a observe method of onCreate of the activity, here is the code:

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_lettura)
        setSupportActionBar(findViewById(R.id.toolbar))

        ...
        Transformations.switchMap(corpoViewModel.getIdTestata()) { id ->
            corpoViewModel.getCorpo(id.toInt())
        }.observe(this, { articoli ->
            when (val count = articoli.count()) {
                0 -> {
                    txtCountArticoli.text =
                        resources.getQuantityString(R.plurals.articoli, count, count)
                    if (bottomSheetBehavior.state == BottomSheetBehavior.STATE_EXPANDED) {
                        bottomSheetBehavior.state = BottomSheetBehavior.STATE_COLLAPSED
                    }
                    bottomSheet.setBackgroundColor(Color.parseColor("#C3858585"))
                    bottomSheetBehavior.isDraggable = false
                }
                1 -> {
                    bottomSheet.setBackgroundColor(Color.parseColor("#3D5AFE"))
                    bottomSheetBehavior.isDraggable = true
                    txtCountArticoli.text =
                        resources.getQuantityString(R.plurals.articoli, count, count)
                }
                else -> {
                    bottomSheet.setBackgroundColor(Color.parseColor("#3D5AFE"))
                    bottomSheetBehavior.isDraggable = true
                    txtCountArticoli.text =
                        resources.getQuantityString(R.plurals.articoli, count, count)
                }
            }
            articoli.let { adapter.setData(articoli as MutableList<Corpo>) }
        })
}

I had the same issue even when i was inserting the rows in my db slowly and i can't get the cause of that error and i can't even realize how can i fix it.

Here is my dao:

@Query("SELECT * FROM corpo WHERE id_testata = :idTestata ORDER BY timestamp ASC")
fun getAll(idTestata: Int): Flow<List<Corpo>>

Here is the Repository:

@WorkerThread
fun getCorpo(idTestata: Int) : Flow<List<Corpo>>{
    return corpoDAO.getAll(idTestata)
}

And the ViewModel:

fun getCorpo(idTestata: Int): LiveData<List<Corpo>>{
    return repository.getCorpo(idTestata).asLiveData()
}

What is the issue of my app crash and how can i solve it?

EDIT:

i'm calling the .getCorpo even in the Fragment which is in that Activity
