Symptoms
Can start and run the game with the -dx11 flag, but very low performance.
Noticed in the settings it was running on my RTX3060 instead of my RTX490, changed settings.
Will no longer start and run at all. Simply presents me with a text box that says "successful, OK"
Unable to start and run game to reset graphics.
