While waiting for customer support to respond to your ticket #180612-004041, here are a few additional things you can try with your character to get unstuck.
You can try the /camp command line of the Chat Box to log out. You should then exit the game server, wait 15 minutes, and attempt to log back in.
You can teleport to a friend, party member, or guild member using the contacts, party, or guild menu respectively. This method is free of charge.
You can teleport to a Wayshrine from the map. Please note: This method will cost gold.
