WSL doesn't want to launch

I have just installed WSL 2 but I have difficulties to launch it.

My installation

I did the official installation from Microsoft. Manual installation, I chose "Ubuntu" in the Microsoft Store and it installed Ubuntu 20.04 :

I have a Dell Inspiron 5593, processor Intel(R) Core(TM) i7-1065G7 CPU. I am on Windows 10, version 2004, build 19041.1083.

The issues

When I execute wsl or wsl.exe in the command prompt or power shell, nothing happens.
When I search "wsl" in the taskbar and click on the icon, a Linux terminal appears and disappears quickly.
After I followed the previous points, wsl.exe --list --all --verbose in the power shell gives me :
```
NAME STATE VERSION docker-desktop-data Stopped 2 docker-desktop Stopped 2 Ubuntu Stopped 2 
```

(with a * before "docker-desktop-data")

The only way I have found to launch it is to go to the Microsoft Store, find Ubuntu and click on the "launch" button. Then a terminal opens and I can execute Linux commands without other issue.
When I try to execute WSL commands (except wsl.exe --list --all --verbose) on command prompt or power shell it says my command is invalid and prints the usage informations.

What I tried to solve the problem

Execute sudo apt get-update on a Linux terminal.
Open the Windows settings, clicked "check for updates" and I don't have any update to do.
Make sure "Windows sub system for Linux" is enabled in Windows settings.

WSL Bash doesn't start and tried the two answers

Could be wrong/no default distribution. Try setting the default distribution:

wsl --set-default Ubuntu

If that fails, try unregistering and reinstalling the distribution.

wsl --unregister Ubuntu

then go to the Microsoft store and click Launch.
