Flutter Firebase Works On Real Device Not On Android Emulator

So I'm writing this in case anyone has any ideas. I cannot get Firebase / Firestore working on my Android emulator with my Flutter project.

At this point, all I'm trying to do is sign in anonymously, and check if a document exists by printing something in the terminal to confirm my app has a connection to Firebase / Firestore in a skeleton app.

  firebase_auth: ^3.7.0
  cloud_firestore: ^3.4.6
  firebase_core: ^1.21.1

Sign in anonymously.

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await Firebase.initializeApp();
  await FirebaseAuth.instance.signInAnonymously();

  runApp(const MyApp());
}
...

And call this method to tell me if the document exists (it does).

Future testFirebase() async {
  await FirebaseFirestore.instance
      .collection("fruit")
      .doc("peach")
      .get()
      .then((document) {
    if (document.exists) {
      print("exists");
    } else {
      print("does not exist");
    }
  });
}

Doing this causes the app to hang. Then after about 5 minutes, I get a slew of error messages

However, on my physical devices running Android Go and Android 12, it works perfectly.

I have:

And bearing in mind, the physical device works perfectly from from the start without me having to do much of anything. But after reading Stack Overflow for days, I'm at a loss.

If anyone has any ideas that I haven't tried, please do let me know :) Thanks.

I had the same issue. Firebase components were working with a huge delay. I had to install earlier emulator version. The problem occured only on my old laptop, my PC was unaffected.
