Nav bar not clickable on mobile

Hello!

I’m getting an issue on mobile where the hamburger menu is not clickable for a few seconds. My brother who is a developer says that there seems to be something wrong with a javascript and that it’s likely connected to “assets/js/primary-navigation.js”.

I’m using Chrome on a Google Pixel phone.

Is there a way to solve this? Thanks in advance!
