While creating a new ReactJS App on my Windows 10 machine, I faced the issue as described in the title even though I didn’t update any packages recently.

To resolve this, I tried updating node to the latest version from here. But that didn’t work. So I had to uninstall create-react-app package globally using the following command:

npm rm -g create-react-app

Install it again with:

npm install -g create-react-app

Then it worked fine with creating the App again:

npx create-react-app my-app
