Clintaurus: im thinking my problem might be unique because i have uninstalled galaxy and played the scene over and it still crashed at that very same place. i'm thinking i am just going to have to play without hooking up with shani hehe.
Hi there.
I faced the same issue too.
Tried to uninstall GOG Galaxy as well, but the root cause (I guess) is that game overlay option makes changes in game files and they are still there even if you uninstall the Galaxy client.
So the solution that worked for me is to install Galaxy, switch off game overlay in both Galaxy options and Witcher 3 DLC section (game files will be updated by client). After these changes I played flawlessly for several hours.
Hope it will work for you as well.
