That output doesn't look like it comes from Black itself. Are you sure the bug is not in some editor integration that is invoking Black?

[Nerrror]

Thanks for your quick response. Thats correct, its the output from vscode when I execute black through the editor. If I run black in the console, I get the same error message (with less formatting):

python -m black n:\network\path\to\python\file.py

That sounds like you have a syntax error in your pyproject.toml.

[Nerrror]

Thats it, I didn't catch that. Sorry for the confusion.
