uv errors if the `pyproject.toml` is a directory

Summary

Any uv commands that I executed always return:

error: failed to read from file `/pyproject.toml`: Is a directory (os error 21)

Adding -v to all commands does not return other helpful error messages.

What I have tried:

1. Remove cache
2. Uninstall (includes removing python and tool dirs) and reinstall
3. Remove cache, uninstall (including removing python and tool dirs), and reinstall

Could this be a duplicate issue? If yes, could you provide me the link? Appreciate the help.
