MSIX isn't supported in Docker containers.

This is a Windows issue, not WinAppSDK (whether you run WindowsAppRuntimeInstaller.exe or directly install WinAppSDK's MSIX packages you'll get errors).

Update: I was able to create a new user and then tried to install the MSIX as that user, but still ran into the same error.
