Problem passing through the Subway (Fallout 4)

I go on a pirate, in the quest "At the last line" after the meeting of the directorate, we decide to deal with the BS and the Subway, the synth immediately runs up and says that I have a flood in my chambers, after which Z1-14 talks about the attack on the Steel Brothers subway, and Father also sends me kill Desdemona. As a result, I have to teleport to the Subway headquarters and see the massacre there, but everything is quiet there, I go up to Desdemona - I am talking about my father's assignment and the fact that I will protect them, she says in response that I need to withstand time and find the Patriot. After that, nothing happens. The quest "At the Last Line" stubbornly continues to point at Desdemona, but at the same time she doesn't want to talk anymore. I tried different cracks. Can you please tell me what to do!
