LeanTween.scale seems to run perfectly first run, after it stop to run

When I build my project and run it : 
LeanTween.scale perfectly runs.

When I stop running project and restart, scale stops to run ...

Here the small code I'm using : 
private void Start()
    {
        LeanTween.scale(this.gameObject, new Vector3(5, 5, 5), 0.5f).setDelay(0.2f).setEase(LeanTweenType.easeOutBounce);
    }

Unity version : 2022.1.18f1.
