I am not able to speak with the "Nervous Merchant" at Scorpion Crossing to progress the quest further to complete the objective "Search for witnesses at Scorpion Crossing."

I have seen other players having the same issue, trying different emotes, not getting him to speak with them. I have already completed the previous 4 objectives as stated below.

I have reset the quest and tried again and the same thing happens.

Please assist me in this regard.
