Does win11 can install Kubuntu?

[dongwhfdyer]

I have tried a tons of times on installation of KDE desktop. I downloaded Ubuntu 20.04 from Microsoft Store and tried different way to install a KDE desktop. After following the steps and noticing the "finishing signs", all I can see is the blank and black console as before.
In the picture below, I clicked the sddm choice and restarted the apps because most tutorials requires us to reboot while it's just a app so I restarted the app.
Then I could only see empty console. Maybe I have installed it but I still don't know how to launch it. Or else, I simple didn't follow the right steps. Or maybe, Win11 is not capable of installing the KDE desktop.
But I DON'T KNOW THE REASON. Can someone help me?🙏

Disclaimer. I am not using Windows 11 and not very familiar with Ubuntu.

Do you want to use KDE with WSLg feature or with older X server method? I slightly remember some issues about KDE in https://github.com/microsoft/WSL repository.
