@deCaldas if you're running npm from WSL distro why is your app trying to write in the C:\Windows folder? That's a restricted directory used by the host OS only.

Here's sample output after cloning your home repo:

@elsaco You're right!! That is how it should happen.

Let's say at some point I started working on Windows OS when I was learning and then I made a copy to WSL 2 distro Debian, then I started to make another copy to WSL 2 distro Ubuntu.
And yesterday I ran find . -type d -name "node_modules" -exec rm -rf {} + because I wanted to copy all my repositories to create a backup. And from then on it doesn't work anymore.
I tried uninstalling Ubuntu to install a new one. Apart from all the commands that I could search on the net.

The first thing I saw was that VSCode was not working. The that I see In the terminal was:

u@EjProI:~$ find . -type d -name "node_modules" -exec rm -rf {} +
u@EjProI:~$ cd home
u@EjProI:~/home$ code .
Loading "minimist" failed
Error: Cannot find module 'minimist'

So I follow the path /home/u/.vscode-server/bin/5c3e652f63e798a5ac2f31ffd0d863669328dc4c to install "minimist" and that solved that specific problem. And you know the rest of the story.

Uninstall Ubuntu to install a new one...
