Editor Freezes When Stopping Play Mode During WarmUp()

[YsmanKhamidullin]

Describe the bug

I am experiencing an issue in the Unity editor where the editor freezes if I stop Play Mode before the WarmUp() method completes.
Expected Behavior:
The editor should stop Play Mode without freezing, regardless of whether the warm-up process is complete.

Actual Behavior:
The editor freezes until the warm-up process is complete, making it unresponsive.

What I Tried:
I attempted to cancel the LLM generation using the following code:

private void OnApplicationQuit()
{
    StopAll();
}

private void StopAll()
{
   _llmCharacter.CancelRequests();
}

public void WarmUp(Action onCompleteWarmUp)
{
    _ = _llmCharacter.Warmup(() => { onCompleteWarmUp?.Invoke(); });
}

However, this did not resolve the freezing issue.

Additional Information:

Unity Version: 6000.0.27f1

Steps to reproduce

1. Call WarmUp() at the start of the game.
2. In the Unity editor:
   - Start Play Mode.
   - Do not wait for the warm-up to complete.
   - Stop Play Mode.

LLMUnity version

I faced the same problem.

For me, it happens when I pause the launch of a project in the editor if the use of a video card is enabled. I can assume that it freezes due to the fact that I stop the project before the model was initialized using the video card.

But the problem also lies in the fact that, in principle, my model does not initialize if I turn on the use of a video card and the function does not work on different devices, tested on:

• laptop with a video card - Nvidia Geforce 3060
• desktop with video card - Nvidia Geforce 3070 Ti

Perhaps this is a problem in the editor of the 6000-LTS version, since on lower versions I did not try to run the model using a video card
