Cloning the 4.10 release (https://github.com/nopSolutions/nopCommerce/releases/tag/release-4.10) and running it from power-shell (VS2019 Publish -> dotnet exec Nop.Web.dll) does not load default theme's CSS.
what I see:
There is a `styles.css` file in `Themes/DefaultClean/Content/css`. but the page does not even attempt to load it
