Divi Builder Closing When Adding New Module

Recently I noticed that the slider was no longer appearing on our homepage and some images were not loading. When trying to troubleshoot this, I came across the issue that while I can edit current blocks on pages, if I click to add a new module, the backend divi builder completely closes.

What I've tried so far:
Disable all caching
Disable static CSS
Update WordPress
Update Divi
Enable/Disable Classic Editor
Safe Mode

So far no luck. If I watch the JS Console during the closeout process, I see a number of TypeErrors occur. Any help is greatly appreciated.

 

I'm not sure how to edit my thread so adding on here.

I've managed to bring back the slider and images by adding a CSS rule to force et_animated opacity to 1. Still no luck with the backend visual composer disappearing, however, when I click to add a new module.
