Plugin not working since Optimization

I have installed an optimization plugin on my site and since then my animation doesn’t play anymore on my page, and the image are not stretched anymore.

Here’s a copy of my site with the animation working; https://atlkeith.scavan.xyz/cbb/
and the animation at https://www.custombilletbuttons.com don’t work.

Maybe comparing both page source code could pinpoint to the problem?
Thanks!
