Windows Platform with Ionic 4 - White Screen

I am attempting to build an Ionic 4 application with Cordova 6. The build is successfull using ionic cordova run winodws – --arch"x64" ; however the screen is always white. I tried to open up all the polyfills to see if that was the issue but no luck.
I have also updated my config.xml file to add the following:

<preference name=“windows-target-version” value=“10.0” /?

When i try to open the .sln project into visual studio code 2017 i get tons of ignored icons on the files.
Any help would be amazing.
