Site Origin doesn't work in WP 5.1.1

Hi! After updating to WP 5.1.1 the SiteOrigin biulder doesn’t work. When I go to edit page or article I see the text box completely white and empty, not editable.

Why it happens? Is the theme compatible with this version of WP?

UPDATE: The problem seems to be a compatibility between YOAST and SITEORIGIN.

If I disable Yoast plugin, all works fine.
