Unity Editor Crashes on textToSpeech.Dispose() and Stopping Game

DrDungeonMaster commented 2 years ago

I've just started trying out UnityTTS and it seems to work great, except that when I click the 'play' button to stop running my project, it crashes to Desktop. I thought maybe this was happening because I wrote my own version of TTSDemo that didn't contain textToSpeech.Dispose() on disable, but turns out adding that and then disabling the TTSDemo-equivalent just crashes the game right then.

The code I was testing is extremely simple. This script is added onto the TTS object from the demo scene, which I turned into a prefab. It replaces TTSDemo. Basically, it just gives me a field where I can type messages, and when I press the selected button on a Steam VR controller (since it's a VR project I'm working on), it says whatever was typed in the box. No problem there, it's just afterwards things get nasty.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Valve.VR;
using Voxell.Speech.TTS;

public class TTSTester : MonoBehaviour
{
    public SteamVR_Action_Boolean buttonPressed;
    public float cooldown = 3f;
    public TextToSpeech tts;
    public string speechTextString;
    private float timeSince = 0f;
    // Start is called before the first frame update
    void Start()
    {
        tts = transform.GetComponent<TextToSpeech>();
    }

    // Update is called once per frame
    void Update()
    {
        if (buttonPressed.lastActive && timeSince >= cooldown)
        {
            tts.Speak(speechTextString);
            timeSince = 0f;
        }
        timeSince += Time.deltaTime;
    }

    void OnDisable() => tts.Dispose();
}

In the Unity editor error logs, the stack trace at crash shows that something went wrong with TfLite.

========== END OF STACKTRACE ===========

Looking into the crashdump, the only piece of useful information I can see is this: The thread tried to read from or write to a virtual address for which it does not have the appropriate access.

I've never seen any kind of error like this in Unity before and have no idea how to change TfLite's memory access abilities. Any help or advice would be appreciated.
