Troubleshooting mobile portrait view scrolling left-right

I am trying to troubleshoot a webflow template I used to create my site, which I am having challenges getting to work properly. Among various issues with responsiveness, on a mobile (portrait orientation) screen, the page annoyingly scrolls left and right. How can I troubleshoot this? I tried making the overflow hidden (I saw that advice in a very old thread), but then it prevents me from scrolling at a certain point. There are a lot of interactions and animations in this template that are problematic and this is one of them. Here’s a link to the staging page: https://sentient-sf.webflow.io/
