[reg-era]

This error happens because Turbopack crashes while parsing globals.css through PostCSS. It’s not your app code — it’s a bug in Turbopack/PostCSS handling.

Fix:
Clear build cache

rm -rf .next

Update Next.js to the latest canary (includes Turbopack fixes)

npm install next@canary

Check postcss.config.js: disable plugins one by one, make sure globals.css has valid CSS.
If still broken, temporarily run with Webpack

NEXT_DISABLE_TURBOPACK=1 npm run dev
