I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

The fix was to go back to Firebase 12.6

Same here. I'm getting the same crash on Unity 6 (60000.0.33f1) with Firebase Unity 12.8.0.

Hey folks, I was able to reproduce the behavior. I'll bring this up to our engineers and see what we can do here. Thanks!

Thanks for flagging this. Looking at the logs, it prints out this message:

Your app is experiencing a known issue in the Android Gradle plugin, see https://issuetracker.google.com/328687152

It affects Java-only apps using AGP version 8.3.2 and under. To avoid the issue, either:

1. Upgrade Android Gradle plugin to 8.4.0+
   Follow the guide at https://developer.android.com/build/agp-upgrade-assistant

2. Or, add the Kotlin plugin to your app
   Follow the guide at https://developer.android.com/kotlin/add-kotlin

3. Or, do the technical workaround described in https://issuetracker.google.com/issues/328687152#comment3

The problem is Unity versions tend to be under AGP 8.4.0, and so are hit by this issue. We'll see what we can do to automate a fix, but in the meantime you can either use an older version of the Unity SDK, or something that worked for me was in the Unity project, enable the baseProjectTemplate.gradle file, and add this to the top:

buildscript {
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.22"
    }
}

So, Unity 6000.0.45f1+ will fix the issue without any other changes https://docs.unity3d.com/Manual/android-gradle-overview.html
