WPbakery Issues uninstall it?

working on a site that uses WPbakery. I added some new plugins and then the site started showing errors in numerous areas on different pages,

Warning: Invalid argument supplied for foreach() in /homepages/11/d784073328/htdocs/clickandbuilds/site/wp-includes/shortcodes.php on line 553

and the page takes ages to load in firefox now.

when i deactivate the wpbakery plugin it then doesnt show the errors but the content layout is messed up.

if this is indeed caused by wpbakery will uninstalling it and reinsytalling it fix the issue?

but the thing is i dont want to delete the wpbakery plugin and then lose all the layouts desgned using it. Will that happen if i delete wpbakjery?
