I faced the same issue and resolved it this way. Steps in sequence:
npm uninstall -g create-react-app
yarn global remove create-react-app (If yarn used)
npm update npx
npm audit fix --force
npx create-react-app your-app-name

This is the error I always face.
install node.js
if you already installed that clear your cache using
npm cache clean --force and try again
Your environment has been set up for using Node.js 18.2.0 (x64) and npm.

I had the same exact error. It was because my anti-virus software viewed the react installation as malware.
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.
Also notice that create-react-app required Node >= 14.0.0 and npm >= 5.6 on your machine
For me It's a antivirus issue, update your antivirus and try. I have faced this issue in windows 11.
Scan your pc/laptop with updated antivirus
