You were promoted, moved to a flailing team and a new domain. This is a significant career opportunity and people are showing trust in you. I would focus on what is needed in the new area. Somebody else recommended you speak with the senior director who promoted you, to clarify expectations. That is good advice.

Yeah seconding this. If you want to think about it in terms of your resume, putting a bullet point or two to tell the story of how your presence moved that team from not performing to performing well would be very beneficial. That's true even if they're not performing because of social problems, because you might be able to provide the team some alternatives to underperforming. Going above senior engineer is not always about solving the technical challenges, and frankly if you're a staff engineer I would expect you to be willing to dig in on social issues within the team or organization where they hinder your technical initiatives.
