Can't log on specific character

Frostmourne server, one of my character can't log in game anymore. When I try, it loads as usual, i see the game for about half a second and then it close the game with this message: https://imgur.com/XUqfAaF

Not happening with my other characters on the same server. What is happening?

teleport that character to HS location via website unstuck:
https://www.warmane.com/account >Services>Select Realm>Select Character>Set Currency:Free>Character Unstuck

If it does not work, try to disable all of your addons before to log-in with that character

Thank you! it worked.
