Cannot install WSL on Windows Server 2019

Missing information

Feedback

I have tried to follow the steps in the page here: https://learn.microsoft.com/en-us/windows/wsl/install-on-server#install-wsl-on-previous-versions-of-windows-server

I definitely have a newer build of Server 2019, WSL is installed and Enabled but when I try and run the step to add the app package for the downloaded Ubuntu distro, I get the following error:

Add-AppxPackage: The 'Add-AppxPackage' command was found in the module 'Appx', but the module could not be loaded due to the following error: [Operation is not supported on this platform. (0x80131539)] For more information, run 'Import-Module Appx'.

I also tried it in an older PS console instead of PS7 and get a different error:
