I had a somewhat similar experience but in my case it was a project that I'm working on my same machine. I'd turn off PC, come after a few days to continue but when I run npm start I'd get the error you are having.

This is how I resolved it:

• Navigated to my project directory
• rm -rf node_modules to delete the node modules folder
• rm package-lock.json
• npm cache clean --force
• npm install
• npm start

I ran into a similar error again, this time I had already uploaded my project in git, so each time I want to work on it, I'd do a git pull project_url then: - npm install - npm start

You need to manually install the create-react-app package again. It will install all of it's dependencies onto your new machine, including react-scripts.

npm install create-react-app

It should be installed as a global and not part of any specific project.
