Hello, I have a problem with my project, after update to the latest version of fmod have silent crash on stop from playmode. No logs, no crash, just editor closed.  
I know which sound doing this but It worked before good. I tried downgrade, change versions but no result.  
The same with changing emitter to event instance.  
Problem is when sound is playing, when I stop it manually is OK. I can stop playmode and again turn on.

this method OnEngineState(0) is in OnDestroy too, to stop sound

```auto
public void OnEngineState(int state)
    {
        Debug.Log($"{name} state: {state}");
        if (state > 0)
        {
            simuEngine.IsRunning = true;

            soundEventInstance = FMODUnity.RuntimeManager.CreateInstance(soundEventReference);
            soundEventInstance.start();
        }
        else
        {
            simuEngine.IsRunning = false;

            soundEventInstance.stop(FMOD.Studio.STOP_MODE.ALLOWFADEOUT);
            soundEventInstance.release();
        }
    }

```
