Unable to edit pages using Beaver Builder

I built a site using Beaver Builder and it has worked just fine for several months. Now client is unable to make any edits.

It has worked fine in the past with all currently installed plugins, but client said it stopped working a few weeks ago.

Beaver Builder is completely unresponsive. I have to click back on the browser button to get out of it.

We need to make edits asap. assistance would be greatly appreciated.
