I updated ArcGIS Pro to version 2.3.0 this morning and updated my installed packages in the Python Package Manager. However, after the update I'm missing the xlsxwriter package that I already had installed before the update. I can find it when I search for packages, but the install won't work for me. I've tried a few times now to reinstall the xlsxwriter package with no luck. Does anyone know why it wouldn't be working?
