Devtools extension load throws error

[kailniris]

win 10 64 bit sdk build
NW.js v0.18.5

I run my project with a shortcut with a target like this:

C:\Dev\nwjs\nw.exe --load-extension="C:\Dev\vue-devtools" "C:\Dev\test"

After the app loads I get the following errror:

Uncaught TypeError: Cannot read property 'Window' of undefined
at get_nw (extensions::nw.Window:754:20)

The devtools says the problem is at this function:

function get_nw() {
  appWindowNatives.FixGamePadAPI();
  try_nw(window).nw.Window.get(); //error is thrown at this line
}

It was working with NW.js v0.18.4

If I run the project without the --load-extension the error is not thrown

Could you please upload the app and the extension?

The app is as basic as possible.
The extension is the vue-devtools extension I downloaded it from the chrome app store.
