Webflow CMS Rollback Needed

I need the site rolled back to an earlier Webflow backup because a recent change introduced functional issues—most noticeably the main navigation no longer works. Your task is to locate the last clean version inside Webflow’s Site Settings, restore it, publish, and confirm that every menu item once again routes correctly on desktop and mobile. No design tweaks or new content are required; I simply want the previous, stable CMS state reinstated and the navigation problem resolved.
