Currently, there are avatars that cannot be used with the message “The secuirty check on this avatar failed and it cannot be selected”, and these avatars cannot be selected as well as changed.
On the other hand, since the avatar must be selected in order to “unfavorite”, it is not possible to “unfavorite” an avatar that has caused these errors.
Can you make it possible to unfavorite without selecting it, or can you just make it not available and allow menu operations?
