failed to log in on all chars

hi, I'm failing to log in on all my chars, after are type pass and authentication code game freezes on loading screen and when I press task manager I realize that game had crashed and gives an error.

I already spoke to a GM Conosgere and at first he fixed my issue by moving my char called blackclaws. however the problem its still persisting and I have donated already a lot to this server and i'm seriously feeling unsatisfied and not well served.

I need immediate assistance ty.
