WPB Front End Editor Stopped Working

When I go to use the WPBakery Front End Editor I get the page loading with fog overlay and the WPB logo showing. This happened all of a sudden. I went over the problem with their support and followed their instructions.

I activated the base theme, twenty twenty, and the editor worked. I activated BlakFyre again and turned off all plugins, loaded a page and got the same result. One by one I activated all of the plugins again but always got the same result. It was only when I used a default theme that the WPB plugin works. I believe this narrowed it down to the theme.

Has this come up with the theme previously and are there any suggestions on how to fix it?

Thanks
