Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Bugs & Technical Problems Divinity II DE DirectX crash on startup

I'm at my wits end. I purchased two copies for myself and a friend and we have both been unable to start the DE. We get two errors. DXGI_ERROR_INVALID_CALL
and E_INVALIDARG. These alternate depending on if we launch with EoCApp or steam respectively.. I want to stress that I have literally tried every single "fix" I have seen from the Audio default changing to uninstalling all my anti virus and disabling windows defender. If I didn't gift a copy I would have already asked steam for a refund.

We are both on WIndows 10 but have different hardware setups. We are getting the exact same errors related to direct X. Classic launches fine but DE will not work at all.

EDIT: An update: While changing NO settings, I got it to start up once. I couldn't my friends to start up even following the same exact steps I took, however upon closing the game I am no longer able to start it up again (same errors as before). Literally NOTHING was changed between the successful launch and the failure.

EDIT 2: Classic no longer launches. Not even a second after starting game it crashes to desktop with a DMP file in the folder. No settings were changed. Nice
