Microsoft have updated the ISO of Windows 10 19H1 for Windows Insiders. The build is 18343, which includes the same content as 18342.8 that Microsoft released to the slow ring last week. You can use the ISO to perform clean installs of Windows 10 19H1, and you can use it to do an in-place upgrade of an existing install if you are having issues going through Windows Update.
You can get the ISO directly from Microsoft.
