Cant access Sekhema

I have the problem that i dropped the quest item to get to the Sekhema trials and now my quest says that i have to go back to the caravan and talk to zarka but zarka doesnt have any quest related text and i cant continue with the quest or even reach the trials.
I cant tp to a friend at the trials , it will just say i dont have the quest progression to get there and there is even no waypoint.

Unfortunately this bug has been going on for a while with no current workaround. A character who loses their first green (quest) Barya like this will never be able to do Sekhemas until this is fixed.
