Additional Information

The code used with my app:

const { app, BrowserWindow, ipcMain, shell, Notification } = require('electron');
const path = require('path');
const date = require('date-and-time');
const fs = require('fs');
const cmd = require('node-cmd');
const ExcelJS = require('exceljs');
const {getDesktopFolder} = require('platform-folders');


let windowsClosedIf = false;
let values1toIpcRenderer = {};
let sendToIpcRenderer = false;

const createWindow = () => {
  // Create the browser window
	const mainWindow = new BrowserWindow({
		// frame: false,
		autoHideMenuBar: false,
		width: 800,
		height: 650,
		icon: __dirname + '/files/icon.ico',
		webPreferences: {
			nodeIntegration: true,
			contextIsolation: false
		}
	});

	mainWindow.loadFile(path.join(__dirname, 'index.html'));
	
	mainWindow.webContents.openDevTools();	
	// mainWindow.webContents.setDevToolsWebContents(devtools.webContents);
  	// mainWindow.webContents.openDevTools({ mode: 'detach' });
		
	setInterval(() => {
		if (windowsClosedIf == false){
			if (sendToIpcRenderer == true){
				mainWindow.webContents.send('valuesTest', values1toIpcRenderer);
				values1toIpcRenderer = {};
				sendToIpcRenderer = false;
			}
		}
	},500);
};

// If Electron is ready, create windows
app.on('ready', createWindow);

// If all windows are closed do...
app.on('window-all-closed', () => {
	windowsClosedIf = true;
	app.quit();
});

ipcMain.on('openExcel', function(event) {
	// .
	// .
	// .
});

ipcMain.on('awsde2x', async function(event) {
	// .
	// .
	// .
});

ipcMain.on('valsX2', async function(event, data) {
	// .
	// .
	// .
});
