[Bug]: App Crashes on Android SDK 33 with java.util.ConcurrentModificationException (com.onesignal.common.events.EventProducer.fire)

What happened?

My App Crashes on Android SDK 33 with java.util.ConcurrentModificationException (com.onesignal.common.events.EventProducer.fire). I am running on Expo. SDK 49 managed work flow. The app crashes immediately the OneSignal tries to initialize. However, if I removed Onesignal, the app runs successfully. It also runs on lower Android SDK versions. On Android 33, it gives the following errors;

java.util.ConcurrentModificationException (com.onesignal.common.events.EventProducer.fire) java.lang.NullPointerException (com.onesignal.core.activities.PermissionsActivity.onRequestPermissionsResult)

My code is below


 const oneSignalAppId = Constants.expoConfig?.extra?.oneSignalAppId;

  OneSignal.initialize(oneSignalAppId);
  OneSignal.Debug.setLogLevel(LogLevel.Verbose);
  OneSignal.Notifications.requestPermission(true);
  OneSignal.setConsentRequired(true);

 OneSignal.setConsentGiven(true);

  let permission = OneSignal.Notifications.hasPermission();
  if (!permission) {
    OneSignal.Notifications.requestPermission(true);
  }

//Method for handling notifications received while app in foreground
  OneSignal.Notifications.addEventListener("foregroundWillDisplay", (event) => {
    event.preventDefault();
    // some async work
    let notification = event.getNotification();
    saveThisPushNotification(notification);
    // Use display() to display the notification after some async work
    event.getNotification().display();
  });

  // Method for listening for notification clicks

  OneSignal.Notifications.addEventListener("click", (event) => {
    console.log("OneSignal: notification clicked:", event);
    const { action, notification } = event;
    saveThisPushNotification(notification);
    notification.display();
    // Alert.alert(notification.title, notification.body);
  });

if (Object.keys(userData).length != 0) {
    OneSignal.User.addAlias("userd", userData.username);

    OneSignal.User.addTag("userid", userData.userid.toString());
    OneSignal.User.addTag("fullname", userData.fullname);
    OneSignal.User.addTag("username", userData.username);
    OneSignal.User.addTag("usertype", userData.usertype);

  }

Steps to reproduce?

1. Setup managed-flow Expo project
2. Install onesignal-expo-plugin version 2.0.2
3. Install react-native-onesignal versioon 5.0.4
4. Configure OneSignal in App.js
5. Run the Development Build of the app on Android SDK 33
6. App crashes at startup

What did you expect to happen?

I expected the application to run normally like in other lower Android SDK version and initialize OneSignal

OneSignal Expo SDK version

2.0.2

Platform

Android
