Using node version 12.2.0 and npm version 7.20.0

Answer 1

This answer looks like it might be related.

Although, I'd suggest upgrading your version of NodeJS to the latest of 12.x or up to 14.x if possible first.

You'll also want to make sure you're getting the latest create-react-app as the issue could be with an older version of NodeJS conflicting with create-react-app .

After you've updated things, I'd use npx create-react-app assessments from the create-react-app guide to create your app to see how things go.
