I have updated all firebase pacakges in my project 8.6.1 and I can confirm that I’m still seeing this crash. It doesn’t happen 100% of the time, but >50% of the time on my test device (Samsung A10). The errors I’m seeing are coming from the device itself via ADB, and unfortunately the stack trace stops about where @kolobokspb’s does.

Yes it’s solved.

Okay, I can confirm that I can repro in a blank Unity project. Here are the steps for minimal repro @paulinon:

Create a new blank project in Unity (I chose 2D template). I used Unity 2021.2, but other versions may be affected.
Import GoogleMobileAds-v6.1.2.unitypackage (latest stable at time of writing)
Import latest stable FirebaseAnalytics.unitypackage. Presumably any Firebase package would work; we just need the core library after all.
Create this script (below) and add it to the scene
Supply an AdMob app ID in the admob config ScriptableObject. Any string should work.
Switch build target to Android and build & run to device
It should crash

using Firebase;
using Firebase.Extensions;
using GoogleMobileAds.Api;
using GoogleMobileAds.Common;
using UnityEngine;

public class ReproductionTest : MonoBehaviour
{
    private void Start()
    {
        MobileAds.Initialize(_ => MobileAdsEventExecutor.ExecuteInUpdate(() => Debug.Log("admob done")));
        FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(_ => Debug.Log("firebase done"));
    }
}

I haven’t attempted a workaround (I should sleep) but I wonder if forcing these libraries to initialize in serial (one to wait for the other before loading) would work.
