I’m not sure if this is site specific but after an auto update of Beaver Builder (Standard) early this morning, a Gravity Forms - form that was using the Beaver Builder - WordPress Widgets > Form, stopped displaying the form. What is odd is I could go edit that page and it would work. I could even Publish the page and it showed the form (guessing cached). However, as soon as I refresh the page the form is gone and an empty spot is displayed on the page. This seems to have just happened with the latest BB plugin update.
To fix the issue for now, I changed the [WordPress Widgets > Form] to [Stand Module > Text Editor] and I just used the Gravity Forms shortcode.
e.g.
[gravityform id="1" title="false" description="false" ajax="true"]
