Visual Editor Not Loading Properly

Builder content link

What are you trying to accomplish
Load and edit pages using the visual editor.

Builder was working perfectly but now the page editor is unresponsive and sometimes loads other times not. When it does load, it’s not functional and doesn’t allow you to edit or scroll on the page. Sometimes I can reach it from the browser on the front-end other times it just sits loading on a white page.

Not sure what changed? It’s affecting all my pages even when trying to load the builder-demo page that came preconfigured with Builder.

I’ve restarted my server, cleared cache and cookies, tried on incognito, but nothing has helped.

Seeing many errors in console, such as:
Uncaught (in promise) Could not evaluate in iframe, doesnt exist! - main.bec947cc.chunk.js:2561
