"All the other feedback I got from my team was overwhelmingly positive."

If this is true, then you have nothing to worry about. The complaining person is an underperforming outlier and the rest of the team would be eager to use your feedback to get rid of them.

However, something about this story feels off. It could be a Byzantine fault - multiple parts of the story being untrue, creating a false overall picture. It could well be that you're actually creating an atmosphere of fear where others agree with you because that's the easiest form of conflict resolution.

If your manager is saying "resolve your differences" and not taking sides, it could be that you're both seen as troublesome.

It is indeed hard to take a step back and view without my own biases. I definitely have had my faults. I sometimes respond in a short and direct way that can be seen as aggressive. I can agree that I am part of the problem, but I have a hard time seeing myself as the one creating most of the problem, fear, especially given all the signals that I am doing well at my job (recent peer recognition of achievements, recent promotion) with the exception of this issue.

So maybe you are right and time will tell how this will go.

edit: actually is there a strategy I can get honest feedback from other coworkers if indeed I am creating fear in the team as you say? I would want to know so I can stop whatever I'm doing.

Feedback from your boss or anonymous feedback helps. One on ones help in identifying these things too. This is difficult to do without management, but you might be able to propose it.

Though as long as you are aware of it and checking the tendency to do so, it should be fine.
