Can you uninstall and try creating a new folder and installing simply on the root of the letter drive instead of under the Program Files directory? E.g.: F:\NostlariusBegins\World of Warcraft Classic
EDIT: Now that I think about it, I recall it not hurting to move the entire game's contents around on you PC provided you move the entire folder and all its contents. Instead of taking the long way with an uninstall/reinstall, try cutting the World of Warcraft Classic folder out of your Program Files (x86) folder and simply paste it on the root of your F: drive. E.g.: F:\World of Warcraft Classic. Then try opening it, logging in, and test changing your settings then closing WoW.
