Huge empty space on mobile site

On the mobile version of my landing page, there’s a huge blank white space on the right of the entire page when you scroll to the right.

I can’t see any elements that overflowed to create this empty space. Any advice is greatly appreciated! Thank you.

Here is my site Read-Only: LINK

I came from the wellcome section.

Something in it is too large. Put this section on display none and no more white space.

Solution : inspect element to find the culprit.

Easy solution : set the section to 100vw and the overflow to hyde.

In some case this king of problem prevent animation to work properly. Be carefull.

Have fun.

Nice site.
