This happens on Windows when a file lock or lingering process prevents Turbopack from unlinking the junction in .next/dev.

Quick fix:

1. Kill any background Node processes:

   Get-Process node -ErrorAction SilentlyContinue | Stop-Process -Force

2. Delete .next:

   Remove-Item -Recurse -Force .next

3. Restart npm run dev.

If it recurs across rebuilds, enable Developer Mode in Windows Settings (allows standard users to manage junctions/symlinks without lock retention) and exclude .next from real-time antivirus scans.
