server error when using frontend team page editor

I’ve been having this problem for a few days and it has really slowed my work down. whenever an account goes to create a team, the wpbakery frontend editor opens and begins to load infinitely. I have checked their forums and the response was to disable conflicting plugins, but after having disabled all non essential plugins it still does not work. in my console I am getting the following errors while it tries to load:

“Failed to load resource: the server responded with a status of 500 (Internal Server Error)”

“Uncaught TypeError: Failed to execute ‘getComputedStyle’ on ‘Window’: parameter 1 is not of type ‘Element’.

all these happen repeatedly. Any help would be great as I can no longer move my project forward without fixing this.
