Skyrim: Delvin Mallory bug?

I play Skyrim on PS4 and want to unlock all trophies. Now I only need the trophy "One with the shadows". For this I have to do all special orders of the Thieves Guild. To get a special order I have to do five orders in loneliness, Windhelm, Weißlauf or Markath. I have already completed five in one of these cities (I don't know which one. I didn't count) and if I want a new order from Vex now, she only says that I should do the special order from Delvin first. But when I go to Delvin, he just says, "Well, your activities seem to be getting around out there. The guild is on everyone's lips again. In fact, I just got a special order. There hasn't been anything like this for years." But does not open a dialog or I can't interact with it. What do I have to do so that I can accept the order? I don't want me to make a new score just for the one bug, because the Thieves Guild quest line is quite long.

Check your quest journal. Really look if there's nothing. Then try to jostle him. So that he pushes back. If that doesn't help, just leave the room.

if that didn't always help. Go to loneliness or something and wait 48 hours there. Then back to delvin

This may help

Have already visited the site and unfortunately it didn't help.

There's nothing in my quest journal that has anything to do with the Thieves Guild. I have once shouted at Delvin with Relentless Power and have beaten him until he was hostile and I had to pay 1000 gold at Vex. I have now waited 72 hours in solitude and I still can't accept the order.
