Hello, I also had the same problem. I think that when the engine was asking you to locate the Data folder, you have selected the
classic one.
Pay attention to not select "
Steam\steamapps\common\Divinity Original Sin 2\Data" folder, that's the classic one,
instead select "
Steam\steamapps\common\Divinity Original Sin 2\DefEd\Data" folder.
Once you have selected the wrong one it will just crash when you trie to start it. There was a way to change the path, but I don't remember sorry, best suggestion i can give is to reinstall the engine and select the right folder when it asks again.
Hope it will help you
