I am having an issue almost identical to this aswell.
I have the full steam version of the game (not the demo) and have had issues at the same spot.
Right after talking to Talana (at the loading screen for the 'dragon dream') the game has locked up several times. Resulting the in need to Ctrl Alt Del and start task manager and kill DIvinity 2 manually.
I have managed to get past that point a couple times, but have ended up having to replay that part (forgetting to save.. and dieing) and i would have had it lock up roughly 15-20 times at that same loading screen.
I have managed to get past that point and saved so i dont need to go through it again (this is the third time it actually got past that load screen, and did the dragon dream to include the video at the end without a hitch.
All i can say is just be persistant! I'm very stubborn when it comes to locking up games and such and have near infinite patience with things such as this, so iwas able to sit there and load/reload many time until i got past the load screen.
