Builder not working on home page - but is everywhere else!

Hi folks,

Fairly new to WP and BB. I’ve a problem whereby the starting the builder on the home page of our site loads a blank page. The builder works on all other pages, header, footer etc… No new plugins have been installed. I’ve been working on the home page today, and have uploaded a couple of photos, nothing huge though, maybe 200-300kb worth.

The front end of the site works fine and displays how it should.

Any help would be appreciated!
