Release v5.0.3 - ImportError: cannot import name 'ConfigFileFinder'

[vjeeva]

how did you install flake8?

poetry install flake8==5.0.3

unmodified output of flake8 --bug-report

This won't run either, due to the traceback.

describe the problem

what I expected to happen

$ flake8 .

Should just exit 0.

what I'm seeing

I see this both on my local Mac (running Python 3.9.11, Poetry 1.1.14), and my GitHub Actions CI (ubuntu-latest).

commands ran

$ flake8 .

@asottile this is a much wider issue reported by many others, see tholo/pytest-flake8#87 - I think you guys should have a closer look please 👍
