tests:

1. OK - I just closed vsc, and launched it with "Run as Administrator" and run ok, vsc wwas able to connect to my Ubunto WSL2 instance.
2. NOK - closed vsc again, and launched normally (without run as admin) and got above error.

Any suggestion ?
I also see a lots of updates available on Ubunto, shall I update all ?

Thanks.
