One of my characters is broken

While playing, I returned to Kingsmarch through the portal. I sold stuff, threw orbs into chest, and want to go back, but an error has arisen.

I get the message: "Exception ... missing registration 16479"

The game has closed. Now I can't play with that character because I get the same error every time. Other characters are fine.
