I am having this problem when testing RTM builds of Windows 10 / Server 2019 Build 17763.1.
Install from scratch (EN-US version of windows), and select Slovenian keyboard on start of the installation process.
When windows loads for the first time into desktop it shows an error that it can't download "language tools" from windows update ?"Something happened, and we couldn't install a feature."
My PC is connected via gigabit ethernet to the main gateway.
This error message also appears every time i reset my PC.
Is this going to be fixed when 17763.1 will be available on windows update ?
