Stuck on Odysseum

So I have completed the first dungeon with the Cyclopes but the quest is still asking me to go in to get the gold key… problem is, the gold key isn’t in my inventory nor on the pedestal inside the dungeon even though it’s marked as 1/1 when I enter said dungeon … So my progression is locked for the quests and for opening the door near the portal … As Anyone found a way to debug this ?
