Theme is conflicting with WooCommerce Store

My Highen Theme is conflicting with my WooCommerce plugin resulting in not allowing customers the ability to add products to the cart. I have confirmed that it is the theme by activating the default theme and it allowed me to add a product to the cart. Here is a video of what is happening https://www.loom.com/share/25e078a2a4fe4e79ae2ba5e5325ed098?sid=2a40fe5f-ee45-4d41-a04b-674934e4175b

I have also uploaded the same video in case the link does not work. Please help us fix this matter ASAP for our customers cannot buy products.
