Hi @Muking3
Try this

1. Temporarily disable Turbopack (use Webpack)

next dev --turbo=false

---

2. Clean project artifacts

rm -rf node_modules .next

---

3. Install latest compatible Next.js

npm install next@latest
# or
yarn add next@latest
# or
pnpm add next@latest

---

4. (Optional) Pin matching versions in package.json

{
  "dependencies": {
    "next": "15.0.3",
    "@vercel/turbo": "15.0.3"
  }
}

Then reinstall:

npm install
# or
yarn install
# or
pnpm install

---

5. Clear Turbopack internal cache

rm -rf node_modules/.cache/turbopack

---

6. Restart the dev server

next dev

---

✅ Checklist

• Node.js ≥ 18.17 or 20.x
• next@latest is installed
• @vercel/turbo matches Next.js version (if used)
• No nightly or mismatched Turbopack versions
• Caches cleared and dev restarted
