Huge extra margin on right side of mobile version, and no scroll?

Having a bit of trouble with the margins on the mobile version of the site, I’ve made a couple of sites and this is the first time I’ve encountered this.

I believe it may be an overflow/ neg margin problem, but can’t seem to find which part is the culprit, any help would be amazing.


Here is my site Read-Only: Webflow - Breakthrough Case Management

You have to use so many negative margins if you are free contact me on
