Repro Steps

I install wsl using command "wsl --install" in cmd run as Administrator. After I'm back to command line, I reboot the machine. Then when I'm back to Windows 10, wsl continues to install, then error:

Ubuntu is already installed.
Launching Ubuntu...

Thank you for reporting this @Heng-Zhou. Looking at the output it looks like the distribution disk is missing.

Unfortunately the only solution would be to unregister the distribution and then install it again (wsl --unregister ubuntu && wsl --install -d ubuntu)
