Update: degrade the version of black to 22.1.0 and it works. But it looks like it is a bug caused by the newest version of black. You should mention it or fix it :-)

That's weird.. I just tried it with black==22.3.0 and I can't replicate this, is this still an issue if you try again with 22.3.0?

I was having the same issue today. Downgraded black and it resolved
