Chapter 5 bug

I’m playing on xbox one x and my main objective marker doesn’t appear anymore can’t get into Dawson’s mansion

I encountered this glitch too on pc and it happened because I accidentally re-entered the sewers. Although I was still able to enter the mansion after looking up online its location--only the objective marker was gone. After I entered the house the next portion of the mission started and fixed the objective problem. I'm not sure how to help if it won't let you inside.
