I believe this is due to gatsby-plugin-compile-es6-packages does not work for scoped packages in Windows. I’ve investigated and raised an issue for that package, hopefully once that issue is resolve this is fixed as well!

Thanks to @malcolm-kee a fix has been merged & pushed for this dependency. v2.1.0 of the package should resolve the issue.
