Exactly the same situation here. I'm at the point in Act 2 where the crossing the bridge at Moonrise triggers the cuts enemy with Jaheira. The game crashes every single time it starts, and sometimes before - as either the graphics aren't loading properly or the characters (and only the characters nothing else) start flickering and any character movement causes the CtD. Waiting doesn't rlfix it, so it's not a load lag either.

Tried going back to earlier saves in Act 2 and those crash the game too.
I've checked all my drivers, windows updates and firewall...same thing
Tried lowering my graphics settings, and repeating with different saves...same thing.
Tried dirextx11 and Vulkan, through launcher and direct...same again

Before someone asks...No I don't have any mods installed, and it isn't specs related and my pc ran the game moderately fine before Patch 2 (random CtD when quicksaving in a conversation)

Honestly I love this game, but this "fix" has made the game totally unplayable as hell. I can't go 2 minutes without the game crashing
