Customized navigation links are not clickable in Chrome/Firefox, but work fine in Safari

We used custom code for a client’s website to create hover states for the navigation, but now on Chrome and Firefox the links for “Studio”, “Social”, and “Contact” are not clickable. The hover state still works for each of these navigation links, but clicking does not direct to the designated page link. In Safari, the links work as they should.

Any support or tips on how to resolve in Chrome/Firefox? Thank you!

Thank you, Ziggy!
