Fontawesome Icons missing

I’m not sure what happened, but all of a sudden the search icon, top of page arrow, and the previous/next arrows on my blog pages are no longer working. They seem to be fine on the other pages. Just comparing the two, it looks like it’s not pulling in the font awesome file? (https://christineschulzwrites.com/wp-content/plugins/elementor/assets/lib/font-awesome/css/font-awesome.min.css). How can I go about fixing this?
