Flatsome UX builder error

Hello,
I am facing an issue with the flatsome ux builder. Whenever I try to edit the homepage of the site, there is an error stating in the console s.angular is undefined and the UX builder doesn’t finish loading. Rest of the pages I am able to edit using the UX builder but the homepage has this issue. If duplicate the page I can use the UX builder. After marking it as a front page after a few days I get the same error. Please advise.

The page I need help with: [log in to see the link]
