Halo Wars 2 crashing everytime since update

Hi,

I downloaded the update/patch a couple of days ago - and now every time I try to play (in campaign mode - not tried any other modes) it just freezes and then crashes the whole system - which means that it’s completely unplayable.

It seems to load the menus etc all normally, and goes all the way through press to continue to get into the gameplay itself, and then it either black-screens and crashes, or on one occasion, showed the very first image on screen, and then crashed.

Is anyone else having the same issue with the update?

Which update was it? The micopatch?
