Skyrim PS4 warehouse of the East Imperial trading company?

I found a bug with Skyrim again. With the Thieves Guild orders you have to track Gulum-Ei through the warehouse of the East Imperial Trading Company, because my companion (Valdimar) wears heavy armor I kept him waiting at the door, but where I went he came and stood there in front of the door and every time I speak to him he only says: "You have lost nothing here" and therefore I can no longer tell him to follow me, I also can't start a conversation with him, he says this sentence as if if you want to address a guard, even with the command of what to do (press and hold X for a long time on him) I can't order him to go out and now I can't get him away.

Can someone please help me there? Because he has about 7 dragon bones with him that I would like to have. XD

Some companions have "decent morals" similar to guards. Actually, you can only kill him. If you want your companions to assist you with crimes, this is only possible for selected ones. So break in together, ask the companion to steal things, etc.

Load or wait about 30 game days… He will then go back to his standard location and there you can recruit him again! (You will receive a message!) Then he should also have the dragon bones in his inventory!

If you noticed the bug so quickly, why didn't you load the last game? Or have you deactivated Autosave and no longer saved it?
