Auto-update in Windows 10, stucks after downloading update.

See original GitHub issue

electron-builder version: 21.2.0
electron version: 6.0.2

electron-updater version: 4.1.2

Target: Windows 10

Hey, doing auto-update feature in my app. Basically app itself located here - https://github.com/ubergrape/grape-electron/blob/new/src/index.js. For macOS working like a charm, but in Windows stucks after downloading an update, according to logs. Basically after New version <version> has been downloaded to nothing happens.

Here are some logs:
