Firebase C++ SDK: Failed resolution of: Lcom/google/android/gms/common/api/Api$zzf

Question

I'm trying to integrate the Firebase C++ SDK in Unreal Engine 4 with gradle for android.

I have downloaded the latest version of the C++ SDK and I'm linking statically the SDK to my application.

However, when I run my application, I get an error : Failed resolution of: Lcom/google/android/gms/common/api/Api$zzf

Full crash:

My build.gradle:

dependencies {
    classpath 'com.google.gms:google-services:4.3.4'
    classpath 'com.google.firebase:firebase-crashlytics-gradle:2.3.0'
}

dependencies {
    platform('com.google.firebase:firebase-bom:25.12.0')
    implementation 'com.google.android.gms:play-services-auth'
    implementation 'com.google.android.gms:play-services-ads'
    implementation 'com.google.firebase:firebase-auth'
    implementation 'com.google.firebase:firebase-analytics'
    implementation 'com.google.firebase:firebase-firestore'
    implementation 'com.google.firebase:firebase-crashlytics'
}

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.crashlytics'

I have tried the solution given at java.lang.NoClassDefFoundError: Failed resolution of: Lcom/Google/Android/gms/common/API/API$zzf; [duplicate] but it doesn't change anything.

Am I missing a dependency? Where's the problem?
