Page trigger does not work

Hi guys! I just bought a course from Awwwards about animations and now I face some issues with the loading animation triggered by page loads. The animation is called ‘intro-loads’ and after I added another animation called ‘intro-click’ which is applied to a button and a click triggers it, the load animation stopped working. If I delete the click animation, the load animation starts to work again. Can someone take a look at my project and help me?
