As a workaround solution, you can fix this by using the legacy provider for OpenSSL. So, you need to edit the package.json and change the configuration of start and build in this way:

{
   ...

   "scripts": {
        "start": "react-scripts --openssl-legacy-provider start",
        "build": "react-scripts --openssl-legacy-provider build",
        ...

   },
   ...

}

Save the package.json file and execute the command npm start again and your application should start and open the browser with URL http://localhost:3000.
