The problem is simple, I have my index.html in the parent directory and the CSS files in the CSS folder, while I have this folder configuration the live server extension in vs code doesn't auto reload the changes when the CSS file is saved inside a folder , when is in the same directory as the html file works fine.
This error only happens with the WSL2, and also happens with JavaScript files.
Edit: Yes the files are on the Windows filesystem, I have the symlink to the windows folder in my wsl.
