Conda update fails due corrupt jupiterlab widgets archive

conda update fails when downloading an apparently corrupt jupiterlab widgets archive

InvalidArchiveError("Error with archive C:\Users\…\anaconda3\pkgs\jupyterlab_widgets-3.0.16-py313haa95532_1.conda

I found a work-around that seems to solve the problem by first separately downloading and installing the problem archive and then proceeding with the conda update --all.
