Completely broken white pages when using Elementor Full Width template.

A client made me aware of an issue on their site this morning. Multiple pages were showing as completely blank, with no error in the console, no content in the html body or head, and nothing printing out when using WPDebug.

After some tinkering, I have identified that this issue is happening specifically on Elementor Full Width pages. Switching to a Canvas page will correct the problem and the page will show. This makes me think it is something in the Elementor header that is causing an issue.

Is this a known problem? Is there some way to fix this? The client’s site is completely unusable right now and has been for over an hour.
