I started with the English evaluation ISO of Windows Server 2019, selected the Standard with GUI installation option, updated the resulting Windows Server 2019 Standard install to the latest OS Build 17763.168 (checked via running WinVer.exe) using Windows Update, and then I walked through all eight of the manual install steps listed above. After two or three server restarts, Get-WssConfigurationStatus -ShowProgress indicates 100% progress and zero errors. After that, the server Dashboard application starts up and runs just as expected.
