maplibre build-dev "TypeError: defaultLoader is not a function"

[SPBNike]

Getting the error below trying to build maplibre on my Windows box. Followed the CONTRIBUTING.md steps (node, windows-dev-tools, npm i, ...) and I'm currently stuck on this error.

I've paved clean the repo, reinstalled node / windows-dev-tools, ... but it still occurs.

d:\gdev\maplibre-gl-js>npm run build-dev

> maplibre-gl@2.1.7 build-dev
> rollup --configPlugin @rollup/plugin-typescript -c --environment BUILD:dev --verbose
