WSL2 and WSL2 distribution is not the same. WSL2 is the platform for Linux distributions on Windows. You need to install a WSL2 Linux distribution.
You can install distributions from the Microsoft Store, but if I remember correctly, you can also open the Start menu, search for “bash” and when you first start it, it will install a default distribution and will ask you to create a user. After that, you will have a WSL2 distribution.
PS.: I deleted your other topic in which you shared the same screenshot. Let’s not discuss the same thing in two topics and we are still discusing the same topic you started here.
