openSUSE Tumbleweed unpins black and currently uses 21.12b0. It even ignores that black pins tomli to <2 until black 22.1.0

tomli 2 expects a BinaryIO object.

I believe these issues and the mentioned change will be available in 0.9.0, which I intend to release today. If not, please open a new issue.
