Code Block with CSS Animation Only Works on One Specific Page

Hello,
I’m experiencing an issue where HTML/CSS code in a Code Block element works on ONE page only, but fails to execute on all other pages and posts.

Code Block Settings (identical on all pages/posts):

“Add codeblock to content” is checked
“Escape HTML Code” is OFF
“Disable Shortcode Processing” is OFF

Setup:

Using Advanced Layout Builder for both pages and posts
Classic editor for posts

What I’ve Tried:

Cleared all caches (browser, SiteGround, Enfold dynamic files)
Added CSS to Quick CSS with HTML-only in Code Block
Used identical Code Block settings across all pages/posts
The typewriter animation works on ONE page only, fails everywhere else

Examples:

Works perfectly:https://debral44.sg-host.com/eilersunfiltered/

Doesn’t work: all other pages or posts.

Why would identical code with identical settings work on one page but not others? Is there a page-specific setting affecting Code Block execution?

Thank you for your help!
