Menu Button on Mobile Site Stopped Working

My mobile site menu icon was working fine and is now not opening, unsure if there has been an update or anything…

It is working fine on the preview, however, when I shrink my desktop browser and also on my iPad and iPhone it doesn’t work. On desktop, the menu icon is showing as clickable (mouse changes on hover).
