PHP Errors: undefined variables and invalid arguments

Hi – I am having trouble with my site and dont know how to fix. When I have the pagebuilder plugin enabled I can’t edit pages or customize appearance of the theme. My debug log is showing PHP undefined variable and invalid argument errors. Any thoughts on how to fix this? Thanks!
