Isso ocorre em qualquer tela?
Com WPF, não lembro se já tive esse problema, mas geralmente isso está relacionado a um problema no código. Quando você tenta abrir o designer, ele identifica o problema no código (no caso, XAML) e gera a exceção. Verifique se não há no XAML nenhuma referência a um objeto que não foi instanciado (como para DataBinding).
