Updating Hugo broke website

I made a website using the Ananke theme and GitHub pages. I updated Hugo, and now when I run “hugo server” I get the following error:

error building site: TOCSS: failed to transform “/ananke/css/main.css” (text/css). Check your Hugo installation; you need the extended version to build SCSS/SASS with transpiler set to ‘libsass’.: this feature is not available in your current Hugo version, see Frequently asked questions | Hugo for more information

I’ve tried uninstalling and reinstalling Hugo to try to make sure I’m running a current version of Hugo Extended, but nothing ever changes. In fact, the output when I run “hugo version” stays the same too- it looks like this:

hugo v0.124.0-629f84e8edfb0b1b743c3942cd039da1d99812b0 darwin/arm64 BuildDate=2024-03-16T15:44:32Z VendorInfo=gohugoio

Here is my repository: GitHub - skhelmbrecht/skhelmbrecht.github.io

Here is the theme: GitHub - theNewDynamic/gohugo-theme-ananke: Ananke: A theme for Hugo Sites

If you were running the extended version, the version string above would include the word “extended”.

The site build without issue with latest hugo extended version.
