Css stops working on production builds

[AssisrMatheus]

I'm working on my personal website, and while the css works locally. Every time I deploy it to vercel, or run next start, the css doesn't work and I can't find the culprit.

You can look at the issue here:

This is the repo of said website. The current deployed version is at "master" branch:

I was wondering if it was tailwind purge css but even after turning it off it still didn't work. I need some external eyes help to try to see what I'm not seeing.
