Horizontal Scroll Bar Issue on Horizontal Scroll Page

Hey there, i am currently working on a horizontal scroll portfolio site. I followed some tutorials i found online but i couldn’t fix the following issue:

I used overflow-hidden and with a lot of trial and error i still couldn’t fix the horizontal scroll bar at the bottom. This bar is only visible when the site is uploaded.

Here is a link to the uploaded site: [LINK]
Here is my site Read-Only: [LINK]
(For Horizontal Scroll in Read-Only, disable preview mode once and enable again, otherwise it is not working for me)

I am no expert with creating a website but i got some experience and tried out everything that came into my mind.

If you know how to solve this issue please let me know, i don’t know what to do anymore.
