Dalaran ERROR

Hey ppl,

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.

Anyone know how to fix this?
I'd be much obliged.

Perhaps it's a corrupt file, did you try redownloading?
