I've got the exact same problem, and we both have a lot of mods in common (unlike you, I don't have any mods in my knowledge that modifies whatsoever Windhelm though, except maybe Open Cities). Did you manage to fix the problem? If so, how so? Thanks in advance. N.B.: I've tried a lot of things, including BOSS-ing, TESVEdit-ing, using the default .ini-s, deactivate a lot of mods, and even loaded a Vanilla save w/ the mods acivated (so it's not save-related) and I still crash when trying to enter Windhelm... However, amongst my numerous attempts, I sometimes managed to pass through the doors but it became ultra laggy, maybe because what's causing the CTD was still loading... Also my Papyrus Log didn't help for me. I was wondering if a real crash log existed to solve the problem as the Papyrus Log isn't one... What was loading when the CTD occurs is without any doubt the cause of the problem, I am surprised I didn't find any programm that can trace this kind of information. [I'm French, sorry for my possible mistakes.]
