    }
  }
}

public/electron.js:

const { app, BrowserWindow } = require('electron');
// const isDev = require('electron-is-dev');   
const path = require('path');
// const url = require('url');
let mainWindow;
 
function createWindow() {
    mainWindow = new BrowserWindow({
        width:800,
        height:600,
        show: false
    });
    // const startURL = isDev ? 'http://localhost:3000' : `file://${path.join(__dirname, '../build/index.html')}`;
    const startURL = `file://${path.join(__dirname, '../build/index.html')}`;
    // mainWindow.loadURL(url.format({
    //     pathname: path.join(__dirname, 'index.html'),
    //     protocol: 'file:',
    //     slashes: true
    //   }));
    mainWindow.loadURL(startURL);
 
    mainWindow.once('ready-to-show', () => mainWindow.show());
    mainWindow.on('closed', () => {
        mainWindow = null;
    });
    
}
app.on('ready', createWindow);

Whenever i try to run the commands, the setup file is created but it is showing only white screen, and when i try to run it simple i.e normal electron cmd to run the react project in app window it runs successfully.
