Published pages hang indefinitely after enabling "Run custom code in Preview" โ€” even on pages with zero custom code

Custom Code

Hi all,

I'm running into a strange issue after enabling "Run custom code in Preview" in Site Settings > Custom Code, and I'm hoping someone's seen this before (Webflow Support pointed me here since it's custom-code related).

The issue: several pages on my PUBLISHED site hang indefinitely with a loading state and never finish rendering. This happens in incognito/private browsing, across multiple browsers, and after fully clearing cookies and cache.

The part that's really confusing me: my Contact page hangs, but it has ZERO custom code on it at all โ€” no embeds, no scripts, nothing. Meanwhile my Services page, which has the MOST custom code on the whole site (two interactive accordions built with Code Embeds), loads and works perfectly.

If I toggle "Run custom code in Preview" back OFF, the affected pages load normally again (obviously without the custom code running).

Plan: Core Workspace + Premium Site plan

Has anyone else run into pages hanging like this after turning that setting on? Trying to figure out if this is a known bug or something specific to my setup. Happy to share more details if helpful.

Thanks!

Paul
