Window does not render on build, works fine in development server

My app does not display a window when it’s built, but works fine when I run npm run serve

There is still an process running in task manager, and the same thing happens if I use the installer. I don’t get any errors warnings from electron-builder.

background.js:

import { app, protocol, dialog, BrowserWindow, ipcMain, shell } from 'electron'
import { createProtocol } from 'vue-cli-plugin-electron-builder/lib'
import installExtension, { VUEJS_DEVTOOLS } from 'electron-devtools-installer'
import path from 'path'
import fs from 'fs'
import childProcess from 'child_process'
import ncp from 'ncp'

const isDevelopment = process.env.NODE_ENV !== 'production'

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win

// Scheme must be registered before the app is ready
protocol.registerSchemesAsPrivileged([
  { scheme: 'app', privileges: { secure: true, standard: true } }
])

function createWindow () {
  // Create the browser window.
  win = new BrowserWindow({
    width: 1200,
    height: 600,
    resizable: false,
    maximizable: false,
    frame: false,
    webPreferences: {
      // Use pluginOptions.nodeIntegration, leave this alone
      // See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more info
      nodeIntegration: process.env.ELECTRON_NODE_INTEGRATION,
      preload: path.join(__dirname, 'preload.js')
    }
  })

  if (process.env.WEBPACK_DEV_SERVER_URL) {
    // Load the url of the dev server if in development mode
    win.loadURL(process.env.WEBPACK_DEV_SERVER_URL)
    if (!process.env.IS_TEST) win.webContents.openDevTools()
  } else {
    createProtocol('app')
    // Load the index.html when not in development
    win.loadURL(path.join(__dirname,'index.html'))
  }

  win.on('closed', () => {
    win = null
  })
}

// Quit when all windows are closed.
app.on('window-all-closed', () => {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', () => {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (win === null) {
    createWindow()
  }
})

I tried the fixes here and here to no avail.

I’m using electron-vue. You can find the full code here if you need more context

Answer

The issue ended up being code present inside of the app.on('ready') function. Any additional code needs to be written after the window is created, or the issue occurs.
