Crash loop on iPhone at app start (EXC_BAD_ACCESS - KERN_INVALID_ADDRESS)

Hi, thank you for fixing the original repo and creating this fork.

I'm having issues with this plugin though: The app works fine at first (when I run flutter run or just run the app through Xcode), but if I terminate the app and start it again, it crashes immediately, and it keeps doing that until I reinstall the app. I looked at the device logs and if I'm understanding it correctly, it's coming from one of the lines we add in the Setup:

Notes:

This only happens on a real iphone, doesn't reproduce in simulator
This reproduces with the example project of this repo as well
It does not crash in release build, only in debug build

I'm new to mobile app developing, and google'd everything I could, yet couldn't find anything helpful. I'd appreciate any help.

Thanks in advance!

Here's my AppDelegate.swift:

import UIKit
import Flutter
import GoogleMaps
import background_locator_2
import Firebase
import FirebaseAuth

func registerPlugins(registry: FlutterPluginRegistry) -> () {
    if (!registry.hasPlugin("BackgroundLocatorPlugin")) {
        GeneratedPluginRegistrant.register(with: registry)
    }
}

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate { 
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
      FirebaseApp.configure()
      GMSServices.provideAPIKey("...")

      GeneratedPluginRegistrant.register(with: self)
      BackgroundLocatorPlugin.setPluginRegistrantCallback(registerPlugins)

      return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}

    override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let firebaseAuth = Auth.auth()
        firebaseAuth.setAPNSToken(deviceToken, type: AuthAPNSTokenType.unknown)
    }

}
