I've also reported the problem here: psf/requests#6331
But I think it's more appropriate to get it fixed in PyInstaller.

Also hit by this, will likely work around it for now by pinning older version of charset_normalizer.

Moving the issue to contrib hooks repository, where we will add a hook (and a test) for the charset_normalizer.

Until then, use --hiddenimport charset_normalizer.md__mypyc with your PyInstaller command.

I've gone ahead and hit the release button in the hopes that I won't be receiving a new duplicate of this bug report each day for the next two weeks.

pip install "pyinstaller-hooks-contrib>=2022.15"
