I was getting Pink screen. I recently allowed a Windows update which resurrected Xbox Overlay (from the dead). It was producing an error box during swtor loading: You'll need a new app to open this ms-gamingoverlay.
This error box pulled me out to desktop, which stops my video card from loading, and then Pinkscreen. Windows:settings:Xboxgamebar:disable, and fixed. A thrilling Halloween scare from MS.
