Access violation at adress in module

[amaia]

Hola!

Estoy diseñando una aplicación y de repente, al intentar modificar el name de un DataModule se produce el error y no me permite cambiar dicho name.

En los detalles del error aparece lo siguiente, ¿alguien me puede echar una mano para interpretarlo?

Mil Gracias
