Hamburger menu works in preview, but not when published

Hi all!

So this has been stumping me for much too long now - I have this hamburger menu that works perfectly fine in preview, but it doesn’t seem to be working when I publish the website to my staging link. Same goes for some hover animations I created that are nested within aforementioned menu. I don’t have any custom code related to either of these elements and I’m at the end of my wits… hoping somebody can help me resolve this.

can you provide the live link?
