Unable to relaunch window after the process crash

[tnah-hcmus]

Hello, i got some troubles.
I tried following guide below in "Relaunch window after the process crash" section, but i got a blank page and unable to reach win.reload() .

win.webContents.on('crashed', () => {
	const options = {
		type: 'info',
		title: 'Renderer Process Crashed',
		message: 'This process has crashed.',
		buttons: ['Reload', 'Close']
	}
	dialog.showMessageBox(options, (index) => {
		if (index === 0) win.reload()
		else win.close()
	})
})

This demo snippet only work with electron 6 below, Can I reload after the process crash in higher version ?
