Why does @import behave like this?

Question

Sass

This is the project structure:

---

I want to include fontawesome. I register in main.scss Everything is successfully connected. But I want this import to be in a file where I include all other fonts, i.e. in _font-face.scss. I register there and give an error during assembly, but if I write the same path as in main.scss, then everything works. But main.scss is one level higher, why is this happening??????
@import "../fonts/FontAwesome/css/all.min.css";
@import "../../fonts/FontAwesome/css/all.min.css";
