Isis's curse "DIGGERIUS'S CODE" is a long term quest.
Diggy encounters many interesting quests while exploring Egypt, but definitely the most problematic ones are the “curse-quests”.
Each Egyptian god/dess puts Egypt under a curse & Diggy needs to lift the different curses by completing all quests given by each god/dess & their priest/ess.
Isis is the 2nd god/dess in line (Anubis - Isis - Horus - Sobek - Bastet - Thoth - Maahes - Ptah - Hathor - Set).
You are able to lift Isis's curse "Diggerius's Code" when you complete all the quests from Isis & her priest.
You do not need to pay attention to the quest "Diggerius's Code".
Just make sure you complete all other currently available quests.....after all quests in Isis's questline are completed....the quest "Diggerius's Code" will be completed, the quest window will disappear & therefore Isis's curse will be lifted.
