Empire Total War - Graphics Error

I was able to run the game for a few weeks, but recently have a serious issue. The game starts up, lets me choose campaign/etc but when I load previous campaign, start new campaign, try a battle - it starts without any error messages. However, while I can see the control panels in the game, and advisors and basically any popup or control center, the game map or battle screen is completely bonkers. Basically a black backdrop with different colored shapes moving across the screen.

I have screenshot, not sure how to attach.
