Describe the bug

• This issue began immediately after upgrading my project from Nuxt 3 to Nuxt 4.
• I have already performed the standard troubleshooting steps including:
  • Deleting node_modules, pnpm-lock.yaml, .nuxt/, and .output/ directories.
  • Running pnpm install to reinstall all dependencies.
  • Clearing pnpm cache (pnpm store prune then pnpm cache clean --force).
  • Temporarily disabling my antivirus software and Windows Firewall to rule out network interference.
  • Restarting my development environment and entire machine.
• The write ECONNABORTED error typically points to a network connection abortion, which seems to occur within the Node.js/Nuxt dev server process, possibly related to HMR or socket communication on Windows.
• This behavior appears to be similar to other reported issues, particularly nuxt/cli#247, which also discusses ECONNABORTED/ECONNRESET errors on Windows during development.

It appears that running the development server with the --no-fork flag has resolved the write ECONNABORTED issue for me. (node 22, pnpm 10.12.1)
