Website hanging up on load

Hey, we are suddenly having a loading problem on our squarespace site, ( futureview.com ). We never saw this behavior before, but when you force a full reload/refresh of the site it might completely fail or just take a loooooong time to load. Using the developer tools it looks like this .js item is the culprit...if I'm understanding it correctly https://assets.squarespace.com/universal/scripts-compressed/extract-css-moment-js-vendor-e67ac5a108455ec4edca7-min.en-US.js

I'm not at all sure what the next steps would be to correct this issue. Would welcome any insight and help to figure it out.

It looks fine to me. But you can try disable all code in Code Injection Header and check again
