chardet 5.0 KeyError with Python 3.10 on Windows #265
Description
Yesterday I encountered a strange CI failure for our Windows GitHub CI workflows which had been running fine until then. The Python 3.7 job passed fine but the Python 3.10 job failed.

The only difference I could find from a diff of the logs was the new chardet 5.0.0 being pulled in. So I pinned chardet to 4.0.0 and CI is passing again.
GitHub Actions Environment:
Virtual Environment: windows-2022 (20220626.1)
Python 3.10.5
Just to note that I also tested same error occurs with windows-2019.
The traceback is rather cryptic since it comes from pytest but this is all there is from the job:
