Max width issue : horizontal scroll

I've been looking for an answer, but no success >< I have a right border on my home page, causing an horizontal scrolling.

When inspecting, I can't see anything being bigger than the 100% max width.. no padding or margin..

I've tried the body > overflow-x: hidden; -- not a winner

Could you check this for me and help if you find the answer please ? :)

This issue is only on the Home Page here

Thank you so much !!
