Crash when exiting application.

[Thxsoft64]

This library is working fine, however if it make at least one SynthisizeAsync call then exit the app, the app crashes. If I don't make the call, it closes fine.

This is the crash result:

To be clear, I have called this several times in testing and it worked fine. But as soon as I exit the app, bang. If I comment out the lines below, no bang.

This is on an M4 Macook Pro using Kokoro.Cpu v0.6.7.

var modelPath = await LoadModelAsync(_ => _outputService.AppendInfo(".")).ConfigureAwait(false); // <- my own loader
using var wavSynth = new KokoroWavSynthesizer(modelPath);
var voice = KokoroVoiceManager.GetVoice(_configuration.Voice.Name);
          
 var bytes = await _wavSynth.SynthesizeAsync(text, voice).ConfigureAwait(false);
