[TurbopackInternalError] Build fails on Windows with Prisma symlink error (os error 1314)

[Shubhamkahar196]

Link to the code that reproduces this issue

https://github.com/Shubhamkahar196/muzi

To Reproduce

1. Use Windows 11
2. Create a Next.js app
3. Enable Turbopack
4. Install Prisma (@prisma/client)
5. Run npm run dev or npm run build

Current vs. Expected behavior

The application should start and build successfully without crashing.

Turbopack crashes and writes a panic log.

Build error:
create symlink to ../../../node_modules/@prisma/client
Caused by: A required privilege is not held by the client (os error 1314)

Provide environment information

OS: Windows 11 Pro (x64)
Node.js: v22.x
Next.js: 16.1.0
React: 19.x
Package Manager: npm
Bundler: Turbopack

Which area(s) are affected? (Select all that apply)

Turbopack, Runtime

Which stage(s) are affected? (Select all that apply)

next dev (local), next build (local)

Additional context

• Running terminal as Administrator sometimes avoids the issue
• Disabling Turbopack resolves the problem
• Panic logs are written to AppData\Local\Temp\next-panic-*.log
• This appears related to Windows symlink permission handling
