Can't enter Chamber of the mind - game keeps crashing

G0x9-SPELPWP1P2NT problem here.

Playing other characters are totally fine, but when I try to enter my Sorc to finish Knowledge Transferring, I can’t get into the chamber and game keeps showing this message.

The server is Enviska, IGN Magiyuni btw.

Im having the same error on an alt I just powerpassed!

Hoping that maintenance tonight doesn’t eat up the pass.

Please help!
