Pagebuilder hangs on loader icon

Hello,

I am using WP latest with wpjobster theme.
If I want to edit pages build with this pagebuilder the pagebuilder hangs on the loading icon.

Since the theme is using a free edition they cannot garantee any support on it. So i am bound to approach you guys directly.

I see a lot of similar Brizy issues reported when searching on Google, but non with a real solution.

I hope addressing this issue directly to you guys will solve my issue once and for all.
