This section: npx : [ "tailwindcss" , "--input=css/app.css" , "--output=../priv/static/assets/app.css" , "--postcss" , "--watch" , cd : Path.expand( "../assets" , __DIR__) ] causes Google Chrome to crash with an Aw Snap message. I'm using WSL 2 with Windows 10 and I can see Live reload reloading the app.css many, many times.
