Exception has occurred. HiveError (HiveError: The box "academictasks" is already open and of type Box<AcademicTask>.)

Question

im using riverpod so im managing state like this

import 'package:flutter/material.dart';
import 'package:hive/hive.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:to_do/tasks/tasks.dart';
import 'package:to_do/utils.dart';

final personalTaskProvider = ChangeNotifierProvider((ref) => PersonalTasks());
final academicTaskProvider = ChangeNotifierProvider((ref) => AcademicTasks());

class PersonalTasks extends ChangeNotifier {

  PersonalTasks() {
    loadTasks();
  }

  List<PersonalTask> personalTasks = [];

  void loadTasks() {
    Box box = Hive.box<PersonalTask>(personalTaskBoxString);
    personalTasks = List<PersonalTask>.from(box.values);
    notifyListeners();
  }

  Future<void> addTask(PersonalTask task) async {
    Box box = Hive.box<PersonalTask>(personalTaskBoxString);
    await box.add(task);
    personalTasks.add(task);
    notifyListeners();
  }

  Future<void> deleteTask(int index) async {
    Box box = Hive.box<PersonalTask>(personalTaskBoxString);
    await box.deleteAt(index);
    personalTasks.removeAt(index);
    notifyListeners();
  }
}

class AcademicTasks extends ChangeNotifier {

  AcademicTasks() {
    loadTasks();
  }

  List<AcademicTask> academicTasks = [];

  void loadTasks() {
    Box box = Hive.box(academicTaskBoxString);
    academicTasks = List<AcademicTask>.from(box.values);
    notifyListeners();
  }

  Future<void> addTask(AcademicTask task) async {
    Box box = Hive.box<AcademicTask>(academicTaskBoxString);
    await box.add(task);
    academicTasks.add(task);
    notifyListeners();
  }

  Future<void> deleteTask(int index) async {
    Box box = Hive.box<AcademicTask>(academicTaskBoxString);
    await box.deleteAt(index);
    academicTasks.removeAt(index);
    notifyListeners();
  }
}

  @override
  Widget build(BuildContext context) {
    return Scaffold(

      ),
      floatingActionButton: const FAB(),
    );
  }

  Widget _scaffoldBody(WidgetRef ref) {
    final personalTasks = ref.watch(personalTaskProvider);
    final academicTasks = ref.watch(academicTaskProvider);

    if (personalTasks.personalTasks.isEmpty &&
        academicTasks.academicTasks.isEmpty) {
      return const Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,

            ),
          ],
        ),
      );
    } else if (personalTasks.personalTasks.isEmpty) {
      return OnlyAcademicTasks(academicTasks: academicTasks.academicTasks);
    } else if (academicTasks.academicTasks.isEmpty) {
      return OnlyPersonalTasks(personalTasks: personalTasks.personalTasks);
    } else {

void main() async {
  await Hive.initFlutter();
  Hive.registerAdapter(AcademicTaskAdapter());
  Hive.registerAdapter(PersonalTaskAdapter());
  await Hive.openBox<PersonalTask>(personalTaskBoxString);
  await Hive.openBox<AcademicTask>(academicTaskBoxString);
  runApp(const ProviderScope(child: MyApp()));
}
