Hi, this is not a bug in the project. It's a Windows filesystem issue (OS error 4390: ERROR_NOT_A_REPARSE_POINT) that happens when the package manager tries to download dependencies from its local cache.

Try these fixes:

1. Clear your package cache:
   • uv cache clean if you use uv
   • pip cache purge if you use pip
2. Check if your project folder is inside a OneDrive or Dropbox synced directory. Cloud sync tools create "reparse points" on Windows and that can break package installations. Move the project to a regular folder like C:\dev\ or similar.
3. Run your terminal as Administrator if the issue persists.
4. If you use OneDrive, try disabling "Files On-Demand" in OneDrive settings.

Let me know if that helps!
