Try with

implementation("com.google.android.gms:play-services-gcm:$project.playServicesVersion") {
    exclude group: 'com.google.android.gms'
}

You can Try including one by one the one which brings errors you apply

 implementation("**API**") {
    exclude group: 'com.google.android.gms'
}

NB $project.playServicesVersion could be any of your versions you are using
