Quest bug Mr. Tommasi (Control)

Hello everyone! Managed to break the quest, who faced and how did they deal with the problem?
Passed the game, decided to study all the locations in detail and climb into all corners, find everything that I missed. He brought me to the turntable and saw the open gate to AMS Sterling, which had previously been closed, went in there and got a fight with the boss as it should be with all the monologues. I killed the boss and went to investigate the game further, returning to the central department, I received the task from Pope to destroy Tommasi, as it turned out this is the boss I had already destroyed. Came back to the point and caught a bug! At the entrance to the location, a monologue sounds again, red barriers close at the exits, and that's it, there are no mobs, there is no boss, there is only a health bar from him and there is no way out of the location either, since you need to fill up the boss for this, which is not there .. And that's it, softlock, restarting the save drops to the nearest control point, the boss strip continues to hang on the screen, heals a full restart, but the quest essentially cannot be completed now. How can the problem be solved? Is it possible to somehow remove the information from the save that I already felled the boss so that he spawns?
