Building Linux from Windows not working.

[rjtayl]

I just got started using cibuildwheel and I'm having trouble diagnosing this issue, any help is appreciated.

I'm trying to build a package in both windows and linux locally, without a CI. The build requires setuptools, wheel, cython, and numpy. The only cibuildwheel option I have is skip = ["cp313-*", "*-win32"]. I was able to get everything working for building windows wheels on windows but when I try to run
cibuildwheel --platform linux
to build in linux it gets stuck at the point where it is copying the project into the linux container:

Copying project into container...

    + mkdir -p /project
tar: Ignoring unknown extended header keyword 'SCHILY.fflags'

and then it hangs there indefinitely. I am using docker desktop. Anybody have any idea what might be going wrong, or what steps I can take to help diagnose the problem?
