I am creating a website it uses WP Bakery, I have finished the entire website, but it is having a responsiveness issue.

As you can see, the website looks fine on the desktop version, but when I am viewing it from a mobile or tablet, it shows a strange white bar at the end, disrupting all the responsiveness. For example, you can see it here: https://imgur.com/a/zB2jLri

Can anyone help me with this? This is somewhat urgent.
