The project `wp-multisite-i18n-nextjs` breaks on Windows

[nicholasio]

Describe the bug

While fixing #866 I realized the project wp-multisite-i18n-nextjs breaks on windows. It seems to be an issue with Next.js itself

Steps to Reproduce

1. Run npm run build on windows
2. Watch wp-multisite-i18n-nextjs break
