I’ve run into this exact issue with Nx on Windows before, and it almost always traces back to overly long command-line arguments or Windows’ default path length limits conflicting with the Nx Daemon. Let’s walk through the most effective fixes, ordered by how quickly they’ll get your app running again:

1. Bypass the Nx Daemon Temporarily #

Since the error notes the Nx Daemon gets disabled, try launching your app without it first to confirm it’s the source of the problem:

NX_DAEMON=false npm run start
# Or run directly
NX_DAEMON=false nx serve

If this works, the issue is definitely tied to the daemon generating excessively long command strings.

2. Shorten Your Project Path #

Your current project path is pretty deep:
C:\Users\Hasan\OneDrive\Desktop\Moniesta-Projects\Moniesta-Combinatioon\moniesta-management\moniesta-admin

Windows has a default 260-character path length limit, and nested paths combined with Nx’s daemon arguments can easily exceed this. Move your project to a much shorter location, like:
C:\dev\moniesta-admin

After moving, run nx reset again and try starting the app—this fixes most ENAMETOOLONG cases on Windows.

3. Full Cleanup & Reinstall #

Cached data can sometimes build up and cause unexpected long arguments. Do a complete wipe of dependencies and Nx caches:

1. Delete your node_modules folder:

   # Windows Command Prompt
   rd /s /q node_modules
   # PowerShell
   Remove-Item -Recurse -Force node_modules
   

2. Delete Nx’s cache directories:

   # Delete project-level Nx cache
   rd /s /q .nx
   # Or clear daemon-specific cache
   rd /s /q node_modules/.cache/nx
   

3. Reinstall dependencies:

   npm install
   

4. Try starting the app again with nx serve.

4. Update Nx to a More Recent Patch Version #

You’re using Nx 13.8.1, and later patches in the 13.x line included fixes for daemon-related command length issues. Update your Nx packages to the latest 13.x version:

npm install @nrwl/angular@13.x @nrwl/cli@13.x @nrwl/workspace@13.x --save-dev

After updating, run nx reset and test the serve command.

5. Audit Your Angular/Nx Configs #

Check if your angular.json has verbose configurations that add to command length:

• Look at the assets array in your project’s build/serve targets—replace dozens of deep, individual paths with broader wildcards (e.g., src/assets/** instead of listing every subfolder).
• Remove any unnecessary flags or arguments in your serve/build scripts that might be bloating the command line.
