Select and copy a text from a TextView in a Dialog

Question

I'm having trouble selecting a text from a textView, every time I long press to select a text the application crashes and I don't understand why. I think it's mainly because the text view it's on a Dialog.

I use the following classes:

TextView:

 <TextView
        style="@style/PUPStyle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/manual_entry"
        android:enabled="true"
        android:textIsSelectable="true"
        android:focusable="true"
        android:longClickable="true"/>

Dialog class:

public class CardReadAlertDialog extends Dialog implements CardReadAlertUseCases {

private LinearLayout mManualInput;
private LinearLayout mReadCard;
private TextView mMessageView;
private Handler mTimer;
private Button btnManualInput;

public CardReadAlertDialog(@NonNull Context context) {
    super(context);
}

@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);

    getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.card_read_alert);
    setCancelable(false);

    findViewById(R.id.btn_cancel).setOnClickListener((view) -> abortProcess(true));

    findViewById(R.id.btn_cancel_read).setOnClickListener((view) -> abortProcess(true));

    btnManualInput = findViewById(R.id.btn_manual_input);
    btnManualInput.setOnClickListener((view) -> createManualInput());

    findViewById(R.id.btn_accept).setOnClickListener((view) -> {
        ManualCardEntry manualCardEntry = getManualEntryFromInput();
        State.getInstance().setManualEntry(manualEntry);

        if (manualCardEntry != null) {
            abortProcess(false);
        }
    });


    mManualInput = findViewById(R.id.manual_input_view);
    mReadCard = findViewById(R.id.card_reading_view);
    mMessageView = findViewById(R.id.read_message);
}

Error log:

You can use and EditText with textviewstyle it should work

<EditText android:id="@+id/showText"
    style="?android:attr/textViewStyle"
    android:background="@null"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"/>
