I also made a bug report here. . Which got suggested to update firebase version. However, the crash still appeared.

Steps to reproduce:

Not able to reproduce locally, but we keep seeing this crash logs from our users in crashlytics.

Relevant Code:

Nothing special, just following guideline as usual. Here is some example crash logs.

Hi @Gong-Tien,

In order to identify what's causing this to happen, could you provide the code you're using to initialize Firebase? You may provide a minimal, reproducible example (with all personally identifiable information scrubbed) as this could be used as a baseline for troubleshooting.

[Gong-Tien]

Sure, here is some part that I can provided.

• We have this code, inside one of MonoBehaviour class.

        public async Task Initialize()
        {
            DependencyStatus result = await FirebaseApp.CheckAndFixDependenciesAsync();
            if (result == DependencyStatus.Available)
            {
                FirebaseAnalytics.SetAnalyticsCollectionEnabled(true);

                FirebaseAnalytics.LogEvent(FirebaseAnalytics.EventAppOpen);
            }
        }

And the above function was called from another Monobehaviour under this function

        public void InitilizationFirebase(Action onInit)
        {
            Initialize().ContinueWithOnMainThread(_ =>
                {
			onInit?.Invoke();
            });
        }

Hope this help

Hey @Gong-Tien, it doesn't look like anything out of the ordinary. But looking at the stacktrace you've provided, SIGSEGV usually means we're trying to read/write a memory we don't have access to. That said, the report mentions delete_FirebaseMessage. Are you calling any code related to Firebase Messaging? If so, could you provide some code snippets for us to further investigate this issue? Thanks!
