Game crashes on login only when logging with my main character

[Aluette]

Game crashes when logging in with one specific character, others work fine. I've tried all methods provided by SE support and then some more. I never actually get to the game, it always crashes during the load screen. The behavior is the same on other computers.

What I've retried:
- Reinstalling game
- Formatting PC (multiple times) and just installing the game (+ steam)
- Updating nvidia graphics driver
- Installing all windows updates, including optionals
- Tried using other computers, same error

If I remember correctly I believe that last time I managed to play with this character the game had crashed mid game with this error. Since then I cannot play anymore with my main.
