Not Working Anymore

Hi,
Our site is built with the page builder. It is causing a 500 server error when we try to edit a page of the site. When the plugin is disabled, all issues go away. We had a developer look into the issue and it was determined that the plugin is having a problem. Specifically, the report said:

For your reference, the page stops processing after this (the below output is generated by strace application and may be useful for the plugin developers / support team to further assist you).

In sequence, the script tried to select some posts with different post_type and is terminated with a segmentation fault error.

****************

Is there a fix for this? Some sort of work-around or are we left to redesign our whole site with a different page builder. Any advice you could provide would be really helpful. The site still seems to work from the front end for visitors but we can’t make any changes now. ??
Thanks,
