critical WPBakery Visual Composer plugin conflict

Hi, Visual Composer is one of the most highly used plugin for my site, but after update to the latest version, it no longer works!

Backend Editor cannot click anything, every function seems like linked to “#” or blank.
Frontend Editor need forever to load and never end.
And every page that originally build on visual composer (which means that it should have contents eg. row and text), now it shows “Welcome to Blank Page, You Have No Content Yet!” and cannot detect any content on the page.

Please look into it asap. It’s really critical issue.
