Reporting this mainly because I'm not the only one who has gone through this.
The error occurs when you change your outfit via your character icon in the upper left hand corner.
Game shuts down and yes a report gets sent to Cryptic, but it's good to share in case someone new comes across this. The more the merrier right?
