Thank you for filing this issue.

Can you please try to install or reinstall aider in a separate Python environment? Either with venv or pipx?

Please remove the existing environment/aider installation first, e.g. with pipx:

$ pipx uninstall aider-chat
uninstalled aider-chat! ✨ 🌟 ✨

$ pipx install aider-chat
  installed package aider-chat 0.58.1, installed using Python 3.12.6
  These apps are now globally available
    - aider
done! ✨ 🌟 ✨
