GitHub Actions Build Successful, But Website Doesn't Reflect Code Changes

[BillyBrown237]

I'm working on a project hosted on GitHub and using a build pipeline with GitHub Actions. While the build pipeline executes successfully, the changes I make to my project files aren't reflected on my live website. Here's a breakdown of what I'm experiencing:

Build Pipeline: My build pipeline seems to be working correctly. It fetches code from the repository, builds it (if necessary), and presumably completes all defined steps.
Code Changes: I've confirmed that the changes I make to my files are committed and pushed to the GitHub repository successfully.
Website Not Updated: However, when I visit my live website, the changes to are not reflected. It displays a crashed verison of the file
