I'm having the same problem, where the screen goes black but the UI remains, music keeps playing, etc. Only way out is to ALT+TAB away then kill the game.
A levelling issue seems likely. It happens during combat the first time I kill an enemy (Seaside Thugs outside Cyseal) or when I complete a quest in Cyseal, triggering XP generation.
I have yet to try the possible work-arounds - will give them a go tonight.
Cheers,
Z
