Blog Posts not showing up, blob/content security policy error related?

on the home page of our site, we’re using the blog posts at the bottom under “Smoke Signals” – the posts stopped showing up. I tried updating WP and the Enfold theme, and cleared the page and site caches, but the posts don’t show up. There is a blob error that I’m not sure if it’s related in console:

Refused to load blob:https://www.shenandoahlodge.org/25a9aeb2-3734-4df9-b38a-451cbb179d4d because it appears in neither the worker-src directive nor the default-src directive of the Content Security Policy.

That is in Safari. Chrome fails silently.
