Sadly, it does not seem to resolve the problem. I've run into the issue
with mypy 0.982 several times today. I am running python 3.10.7.

I've posted to the mypy gitter as well in case it's an issue on their end.
I guess I should add that I haven't seen it running mypy, only running
dmypy. That and the fact that it's not 100% repro does make it seem like a
mypy issue.

I appreciate the attention.
