crashing to main menu after clicking battle.

i physically can't play the game now. it just goes back to the main menu so there's no crash log as far as i'm aware.

I meet the same thing, load the campaign save game and then constantly push back to main menu after a flash show my in game campaign save and boom back to main menu, WTH

I have experienced this as well. There's no error code or anything. Tried restarting the game & my computer to no avail. There was a windows update yesterday; perhaps this is connected? The game crashes back to menu seconds after loading any campaign save.

Seems to have just started today. I've attached my dxdiag results.
