Thanks for the proposition, i’ll think about it!
I manage to have the log files enable for android (it was quite a ride). The main error message is JNI DETECTED ERROR IN APPLICATION: java_class == null
But i haven’t found what to do with it.
A longer sample:
Exception in dalvik/system/DexClassLoader.loadClass: java.lang.ClassNotFoundException: Didn't find class "com.google.android.gms.games.NativeSdkCallbacks" on path: DexPathList[[zip file "/data/user/0/com.Company.MyGame/app_.gpg.classloader/2e190de0913242cfb3e30a895073c67e_games.jar"],nativeLibraryDirectories=[/system/lib64, /system/system_ext/lib64]].

I don’t see crash on pre-launch report menu, but on the screenshot sub-menu, i can see that the Google’s bot manage to get the google play signing pop-up. On several phones with android 13, it crashes when we try to connect with a login fail method, On phones with android 14, it’s just login fail without the crash
Which version of unreal do you use ? (I am on 5.2)
