"You are running create-react-app 4.0.3 which is behind the latest release (5.0.0)"

Try running this:

npx clear-npx-cache

It's fixed. I do npx create-react-app@5.0.0 my-app.

Reference: Error while creating new React app ("You are running `create-react-app` 4.0.3, which is behind the latest release (5.0.0)")

npx clear-npx-cache worked for me.

Try npx clear-npx-cache to clear your npx cache and then running the npx create-react-app your-app.

Additionally, it might be worth trying to force the latest version with:

npx create-react-app@latest my-app --use-npm

It's solved. By using this code:

npx create-react-app@5.0.0 my-app

If it does not work, use this and try again:

Delete everything from C:\Users\your_pc_name\AppData\Roaming\npm-cache

This could be a local caching issue. Try the command npm cache clean --force using administrator mode in your terminal and then try again with the same command - npx create-react-app my-app.

Follow this:

npm uninstall -g create-react-app

npm cache clean --force”

npm cache verify

npx create-react-app my-app

You are running create-react-app 4.0.3, which is behind the latest release (5.0.0).

We no longer support global installation of Create React App.

this works--npx create-react-app@5.0.0 my-app
