For me too, Divinity is crashing when I try to start a new game. The screen darkens and I hear the birds, then crash.
The bug report tool appeared just once, and was already "Canceled".
There wasn't a folder for ..\users\%username%\My Documents\Larian Studios\Divinity Original Sin. I've created one manually, and the game created the graphicSettings.lsx and config.lsx inside.
did it work after that Workaround ?
Noone seems to be interested in our CTD Problem. Can´t Play unfortunately due to that. Updated graphic Card Driver and everything, but still only birds singing, then CTD !
