Splash template preloader not functioning properly

I’m using the Splash template for my site and am having an issue with the Preloader element. It seems that when the site loads, the last step of the animation is not executing - it’s supposed to change the display of the element to none, but instead, it’s remaining on the initial state of flex. This is preventing me from clicking on anything on my site.

Example page: andresrodriguez.io/portfolio

Has anyone else experienced this issue?

I’ve removed the preloader from my pages temporarily so that I can have a functioning site but noticed that it works correctly on the template pages: andresrodriguez.io/template/intro
