Page builder content disappeared

I am using WordPress version 4.71 with AccessPress pro version 2.02 and page builder version 2.4.21.

We have been unable to create new posts or edit pages/posts for several weeks, and also noticed that the page builder tab had disappeared from our pages.

We deactivated all plugins and cleared cache, and noticed that the page builder plugin was prohibiting us from creating or editing pages or posts. However, we have now lost all content and formatting that was created using page builder.

How can I get back my content/formatting and enable page builder?
