Nostalrius Begins - Quality wow vanilla realm (1.12)

I cant log into my Maincharakter "Walktheline" for some reason.
My character is currently in Booty Bay and once the loading has finished, everything loads as it should, but then after a splitsecond the screen freezes and after a short while the game crashes (without any message).

I can log into my other characters.

Need help.

Kind Regards
Walktheline

EDIT: GM relocated my character (inside and outside of booty bay) -> didnt work, deleted WDB --> didnt work either

Seems there has been some issue with the "Questie" Addon. Logging on without the addon worked.

After downloading the latest version of the addon, everything went back to normal.
