Site builder taking long to load

For some reason, now when I try to edit pages with the site builder, one of the sections will get stuck loading. Either the left side with the widget options, or the right side with the row/widget customizations settings.
I have to keep refreshing the page and trying to edit. Sometimes it loads quickly, but it is often stuck in loading and I have to refresh multiple times before it starts loading again.

My domain is biz197.inmotionhosting.com/~thewan19

*I’ve tried deactivating my plugins to see if one of those was the issue and it didn’t help

You can try to reinstall WordPress, Sydney theme, and plugins after making a full site backup (or you can try to do it in staging environment).
