Drag'n'Drop into Electron app is not allowed

问题

I am trying to implement Drag'n'Drop functionality for users to easier upload their images. In browser the drop area works perfectly but Electron is preventing files to be even dropped into the app. Every time I try to drop a file cursor changes to the one shown below and nothing happens.

I thought maybe Electron had configs to disable dropping files by default due to popular complain but I couldn't find any solution.

The picture shows the drop area, but the same issue is all across the app.

Main.js:

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

let win

function createWindow () {
  win = new BrowserWindow({ width: 1000, height: 600, minWidth: 690, minHeight: 340 })

  win.loadFile('index.html')

  win.webContents.openDevTools()

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

app.on('ready', createWindow)

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

app.on('activate', () => {
  if (win === null) {
    createWindow()
  }
})

Ok. That wasn't fun. Looks like something actually broke. But after I restarted the console, Windows then reinstalled the project, Electron, and NPM it finally worked. The problem is now solved.
