Sounds like a known problem where a fieldbus (HART?) alarm list aspect situated at the object where browsing abort is corrupted (it's filter object is gone/missing).
Remove the corrupt aspect or make it point to a valid filter object. If the list aspect is inherited you must first perform "override" to make it writeable.
i had the same problem please follow the recommendation in the last of the following link
