We have not updated the theme with the WPBakery version for a long time. We just focus on the new template of Elementor to develop the theme and support the clients who still use the old version with WPBakery.
You used the WPBakery template and then updated your site with another template (Elementor), of course, your site would be broken because these 2 templates cannot work at the same time.
With version 1.x, the latest version is 1.1.4 so you are in the latest one.
