In UniTask, await directly uses native timing, while `WithCancellation` and `ToUniTask` use specified timing. This is usually not a particular problem, but with `LoadSceneAsync`, it causes a different order of Start and continuation after await. So it is recommended not to use `LoadSceneAsync.ToUniTask`.
> Note: When using Unity 2023.1 or newer, ensure you have `using UnityEngine;` in the using statements of your file when working with new `UnityEngine.Awaitable` methods like `SceneManager.LoadSceneAsync`.
> This prevents compilation errors by avoiding the use of the `UnityEngine.AsyncOperation` version.
In the stacktrace, you can check where it is running in playerloop.
