The file is completely garbled. It mostly consists of

ubuntu-latestrunner, but not on myself-hostedrunner, both using the samecontainer: ubuntu:24.04for testing purposes.I have noticed this is working in
ubuntu-latestrunner, but not on myself-hostedrunner, both using the samecontainer: ubuntu:24.04for testing purposes.The hosted runners have an cached toolchain with multiple versions of python already installed. The action is using that instead downloading an version.
The selfhosted image does not have sush toolchain.GitHub hosted is running on 50Gb+ VMs in Azure to minimize download and install cycles.

Ah, nice spotting.
However it's weird that the deflate header is kept as-is while the
1fbytes are correct.However it's weird that the deflate header is kept as-is while the
1fbytes are correct.The
ef bf bdpattern is a specific symbol: https://www.cogsci.ed.ac.uk/~richard/utf-8.cgi?input=%EF%BF%BD&mode=charThat is the symbol you usually see when UTF-8 is being displayed as ASCII. It looks the files have been treated as text causing all the non-ASCII (i.e. binary) data being treated as unprintable characters thus corrupting it in the process.

All looks good for us at flake8-pyi and typeshed now -- thanks @aparnajyothi-y!
CI now passes at
pywin32for Python 3.13-dev as well! mhammond/pywin32#2260Some good confirmations above. Can confirm it works on our end too. Closing the issue for that reason.
Thanks for the fix! ❤️
