Moreover, I have already tried these suggestions:

1. delete node modules and package-lock.json
2. then ran command: npm update
3. then ran command: npm install
4. and when I ran npm start I got the same error as above

One more thing which I noticed, whenever I freshly install a react app then I used to get App.js, index.js, index.html even a src folder, I am not getting all these. Please help!

我以前也遇到过这个问题，但幸运的是我永远修复了它，您可以通过转到 -> 控制面板 -> 系统和安全 -> 系统 -> 高级系统设置 -> 环境变量查找系统变量并查看对于 ComSpec 确保路径是这样的C:\\Windows\\system32\\cmd.exe并重新启动系统，看看它会工作
