conda package

[baugetfa]

Hi,
1st great project thanks !
Just to report an error with the last conda package build, I have InvalidArchiveError with jupyterlab_widgets-3.0.16-pyhd8ed1ab_0.conda when I tried to install it.
I do not have the error with jupyterlab_widgets-3.0.15.

This on windows, on Linux no problem.

Also seeing this on windows:
