Expected Behavior

after updating create-next-app to 12.1.1, npx create-next-app appname is not creating the Next app

To Reproduce

I tried npx create-next-app@latest appname but it’s throwing the same error.

even I tried to uninstall the create-next-app & reinstalled it but it’s throwing the same error.

and I install yarn globally then npx create-next-app appname run command properly without any error

[JorneSaenen]

same error, ideas?

“npx create-next-app@latest --use-npm”
