Maybe you have an outdated create-react-app version.
If you have npm 6, then you also have npx. Using npx you can just do:
npx create-react-app my-new-app
And it will use the latest create-react-app, even if you don't have it installed.
Check the documentation

Try:
npx create-react-app Secondapp
With the newer versions of npm (version 5.2 and higher), you are recommended to use npx to use create-react-app instead. According to the create-react-app github, you are advised to
uninstall create-react-app:
npm uninstall -g create-react-app
clear and verify cache
npm cache verify
create a react app with npx and start it like
npx create-react-app my-app
cd my-app
npm start

please run the following command in Command Line:
npm cache clean --force
then run
create-react-app <project Name>
if you still getting the problem, uninstall the old and download new and remove all npm folders.
if still didn't help, you can switch from npm to yarn
npm install -g yarn
// Method 1
yarn global add create-react-app
create-react-app <projectname>
// Method 2 work on yarn 0.25+
yarn create react-app my-app

From https://create-react-app.dev/docs/getting-started#creating-an-app
npx create-react-app my-app
(npx comes with npm 5.2+ and higher)
But you used
`create-react-app my-app`
If you use npm 5.1 or earlier, you can't use npx. Instead, install create-react-app globally:
npm install -g create-react-app
Now you can run:
create-react-app my-app
I was also not able to create a new app but when I follow these step
then it works for me.
After a few searches, I found this :
If you've previously installed create-react-app globally via npm install -g
create-react-app, we recommend you uninstall the package using npm uninstall -g
create-react-app to ensure that npx always uses the latest version.
So if you installed create-react-app with
npm -g install create-react-app
just run :
npm -g uninstall create-react-app
npx create-react-app
It should do the job
I was able to solve this problem by,
running
npm cache clean --force
then
npm create-react-app my-app

Use npx (it comes with npm 5.2+).
From the react docs:
You’ll need to have Node >= 6 and npm >= 5.2 on your machine. To
create a project, run:
npx create-react-app my-app
cd my-app
npm start
