Flutter - Fatal Exception: java.lang.LinkageError

Question

I've a Flutter app project and just for some users (7% of my user base) the app crash and Play Store is reporting the following error on android devices:

java.lang.LinkageError:

It seems an admob related issue because I noted the error:

at io.flutter.plugins.googlemobileads.FlutterBannerAd.load(FlutterBannerAd.java:60)

About adMob on pubspec.yaml I use:

  google_mobile_ads : 
    git:
      url: https://github.com/SuaMusica/googleads-mobile-flutter.git
      path: packages/google_mobile_ads
      ref: feature/suamusica

This is my android/build.gradle:

buildscript {
    ext.kotlin_version = '1.5.10'
    repositories {
        google()
        // jcenter()
        // maven {
        //     url 'https://maven.fabric.io/public'
        // }
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath "com.google.gms:google-services:4.3.3"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        // jcenter()
        // maven {
        //     url 'https://maven.fabric.io/public'
        // }
        mavenCentral()
    }
}


rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

// subprojects {
//     project.configurations.all {
//         resolutionStrategy.eachDependency { details ->
//            if (details.requested.group == 'androidx.core'
//                     && !details.requested.name.contains('androidx') ) {
//                 details.useVersion "1.0.1"
//             }
//         }
//     }
// }

task clean(type: Delete) {
    delete rootProject.buildDir
}

Flutter version 2.10.5 stable

Android Studio Bumblebee

Where can be the issue?

Thank you.
