Halo Wars 2 not launching

Hello! I’m having an issue launching a game I bought 3 days ago called Halo Wars 2: Standard edition.

I have tried many different fixes, including:

3 re installations on different drivers
Disabling and re-enabling my graphics card
Resetting and reinstalling the windows store and xbox beta app
Launching it from different apps
Contacting Microsoft support (5 times) to try to find a fix but all of them were either re installations or to contact developers

I have a great gaming PC that can run many things that are much more demanding, but just in-case I will post my specs:

Processor: Intel(R) Core™ i5-4690K CPU @ 3.50GHz (4 CPUs), ~3.5GHz
GPU: Nvidia geforce 1050 TI

I am desperate at this point, and I KNOW I cannot be the only one who has had this issue. I understand you guys have stopped supporting the game, and I understand you guys get tons of questions daily, but i’m unable to play with my friends and it is becoming an issue for me. I am trying to launch the game from windows 10.

I can not launch the game either, and so far no support is coming from Microsoft.

I don’t understand that the game is not supported any more. This was not made clear at point of purchase. If it had said ‘no support or refunds if it does not work for you’ I would not of spent £50.
