Ohh that makes a lot of sense!
Ideas that come to mind are either having a default name for the character or just making the gallery inaccessible before naming your character, synonymous to how you can't access the gallery from the main menu, for example.
Sorry if I come across as a bit pushy or invasive, I'm a programmer myself and I enjoy solving problems haha.
Either way, I wish you good luck on however you fix the bug, and thanks for being so interactive, too!
