So I've gone into the institute 4 times to see if this would fix itself but it didn't. I went with the railroad and desdemona says take this holotape but nothing happens and when I'm supposed to use it I don't have it. I've reloaded, restarted, left the quest and came back and still nothing and at this point I'm level 53 and REALLY don't want to restart so if any of you have a fix that would be great.
