Did something break?

[ghost]

I created a new react project: npx create-react-app my-app.
Ran: npm install
Started app: npm start
Getting Error: Loading PostCSS "postcss-preset-env" plugin failed: Cannot find module 'node:vm'

A fix has already been merged and will be released shortly :

#407

You can downgrade to postcss-preset-env v7.6.0 or update your node version to at least 16 to work around the issue until we publish the fix.
