Steps to reproduce
- run
npx create-react-app myapp
I've also tried various debugging suggestions, such as

Also tried npm cache clean -f and starting fresh with a new package.
Expected behavior
Creates a react app.
Actual behavior
Fails immediately with the error above. Running alternative npm init react-app myapp produces a similar error with a bit more info:
