Try to clean the cache npm cache clean --force than npx clear-npx-cache and run again npx create-react-app my-app or npx create-react-app@latest my-app --use-npm.

If You still have this problem run Try to run cmd as administrator. If You installed create-react-app globaly than run npm uninstall -g create-react-app.

Right-click on the command prompt select Run as administrator and type npm i create-react-app. After installing close the program and make a folder, open cmd, go to the folder and run npx uninstall create-react-app, also run npx uninstall -g create-react-app and after that run npx create-react-app issue resolved.

Use a different network: For example, you can try connecting to a different Wi-Fi network or using a mobile hotspot.

Hope this should help you.This Works For me.
