Render child_process in electron

I’m trying to use child_process to open another program through electron, but when I click the button even calling the function to render it doesn’t open the requested application.

Electron version ^16.0.7:

main.js

const { app, shell, BrowserWindow } = require('electron')
const path = require('path')

let mainWindow = null;

function createWindow () {
  mainWindow = new BrowserWindow({
    autoHideMenuBar: true,
    width: 1300,
    height: 840,
    resizable: false,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
      webPreferences: {nodeIntegration: true}
    }
  })

  mainWindow.loadFile('./app/home.html')

}

app.whenReady().then(() => {
  createWindow()

  app.on('activate', () => {
    if (BrowserWindow.getAllWindows().length === 0) {
      createWindow()
    }
  })
})

app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('web-contents-created', (e, contents) => {
  contents.on('new-window', (e, url) => {
    e.preventDefault();
    require('open')(url);
  });
  contents.on('will-navigate', (e, url) => {
    if (url !== contents.getURL()) e.preventDefault(), require('open')(url);
  });
});

preload.js

window.openGaeme = function(executablePath) {
  let child = require('child_process').execFile;
  child(executablePath, function(err, data) {
    if(err){
       console.error(err);
       return;
    }
 
    console.log(data.toString());
});
}

function in renderer.js

function onClick() {
    var executablePath1 = "C:\Program Files (x86)\Game\system\game.exe";
    window.openGaeme(executablePath1);
}

HTML BUTTON AND SCRIPT:

<button class="button-go" role="button" onclick="onClick()">JOIN</button>

<script src="./core/renderer.js"></script>
