[BUG; CRITICAL] Wrong assetReference.InstantiateAsync(parent).ToUniTask(cancellationToken: token) result

[truenoob141]

I want to spawn 'TutorialMessageView' prefab via next code:

var go = await assetReference.InstantiateAsync(parent)
    .ToUniTask(cancellationToken: token);
            
Debug.LogWarning($"Loaded {go.name}, Must be {typeof(T).Name}");

Before await:

After:

Result is wrong.

Native tasks work correctly:

var op = assetReference.InstantiateAsync(parent);
var go = await op.Task;
token.ThrowIfCancellationRequested();

Debug.LogWarning($"Loaded {go.name}, Must be {typeof(T).Name}");
