관련된 많은 글을 찾아보며 SCSS 파일을 수정해 보았지만 해결되지 않았고, Jekyll 버전에 문제가 있을 것이라 추측하여 GitHub Pages의 Jekyll 버전으로 다운그레이드했습니다.

GitHub Pages: Dependency versions

jekyll: v3.9.3
jekyll-feed: v0.15.1
jekyll-paginate: v1.1.0

먼저, 기존에 설치된 Jekyll을 삭제해야 합니다.

> gem uninstall jekyll

You have requested to uninstall the gem:
        jekyll-4.3.2

jekyll-feed-0.17.0 depends on jekyll (>= 3.7, < 5.0)
jekyll-sitemap-1.4.0 depends on jekyll (>= 3.7, < 5.0)
If you remove this gem, these dependencies will not be met.
Continue with Uninstall? [yN]  y
Remove executables:
        jekyll

in addition to the gem? [Yn]  y
Removing jekyll
Successfully uninstalled jekyll-4.3.2

jekyll v3.9.3로 새로 설치합니다.

Ruby Sass has reached end-of-life and should no longer be used.

* If you use Sass as a command-line tool, we recommend using Dart Sass, the new
  primary implementation: https://sass-lang.com/install

* If you use Sass as a plug-in for a Ruby web framework, we recommend using the
  sassc gem: https://github.com/sass/sassc-ruby#readme

* For more details, please refer to the Sass blog:
  https://sass-lang.com/blog/posts/7828841

빌드에 필요한 JeKyll 플러그인도 새로 설치합니다.

일반적으로 JeKyll을 삭제할 때 플러그인도 같이 삭제됩니다.

설치가 끝나고 페이지를 새로 빌드하면 오류 없이 잘 실행되는 것을 확인할 수 있습니다.
