I have encountered an error message from a character, please help me!

When one of my characters logs into the game, an error window will pop up and the game will automatically close.
The error message is as follows:
Attempted to resume pathing action with an invalid skill:2148073478 object:
Metadata/Monstrs/LeagueRitual/DemonFaction/DemonBurrower@80

All other characters are logging in normally!
What do you need me to do? Or please help me! Thank you.
