I recently stumbled upon what seems an unsolvable problem for me. I have many characters on my main account set in Dalaran and I cannot load them since right after the loading screen ends I get wow error saying:
World of WarCraft (build 12340)
Exe: C:\Users\user\Desktop\Wrath of the Lich King 3.3.5a\Wow.exe
Time: Dec 9, 2020 3:28:15.254 PM
User: user
Computer: USER-PC
------------------------------------------------------------------------------
This application has encountered a critical error:
ERROR #134 (0x85100086) Fatal Condition
Program: C:\Users\user\Desktop\Wrath of the Lich King 3.3.5a\Wow.exe
Failed to read file DUNGEONS\TEXTURES\DALARAN\DAL_WALL01.blp.
I can easily load my other characters in Orgrimmar and Thunder Bluff. I can play them with no problems whatsoever.
I have tried deleting cache and WTF folders, downloading the Large Address Aware and other fixes already mentioned on this forum.
