Title says all. Black screen after a few turns (on every campaign.) It runs smoothly on the campaign and battlemap, but then just blacks out with the cursor and audio still there after a few turns. I've looked up and tried every damn guide available online going back a decade. Acer laptop with i5 cpu and iris xe integrated graphics, no mods. I'd be grateful for any and all help. Just don't ask me if I've tried any of the typical fixes because yes, yes I have, and I will shoot myself in the face if I'm the victim of more bad advice.
