Crash report

Mypy 1.7.0 crashes when importing the most recent version of types_aiobotocore_s3 (2.7.0).

To reproduce:

I have the following file:

# test.py
import types_aiobotocore_s3

I'm getting a Mypy crash when running the following command:

mypy --show-traceback --disallow-any-unimported test.py

Getting same crash on mypy master branch.
