Game crashed during mapping! Now i cant log in because the game keeps crashing again every time.

As title says, i was mapping on my Deadeye and tried to enter the boss arena on the Steaming Spring map when my game crashed.
Now every time i try to log in on that character again, my game keeps crashing. I tried switching client, as this usually kills the instance afaik, but that didnt work.
I can log in on other characters and could even enter the map succesfully, but not on my Deadeye. (who is my main character)
Error code is CE-108255-1
