Unity Android app won't start second time

Unity
1

I’m building an internet radio out of an old phone.

Everything works OK the first time, but on Andriod when I quit the application and then start it again, it won’t.

It doesn’t even show the “build with unity” splash.

When I remove the FMOD part, it starts OK the second time.

Running multiple times in the Unity Editor works fine.

Is there something I should “release” on Application Quit?
Other than what I’m doing now? (I tried with and with an explicit CoreSystem.release(), result is the same)

    void OnApplicationQuit()
    {
        // App is being quit - ensure complete cleanup
        StopStream();
#if !UNITY_EDITOR
        UnityEngine.Debug.Log("FMOD CoreSystem.release()");
        RuntimeManager.CoreSystem.release();
#endif
    }
