Frame rate drops in ME1 cutscene

I’m playing on Xbox Series X, and am seeing significant FPS drop during the cutscene where you first travel to the Citadel in ME1, causing stuttering on a 120hz TV.
It occurs in both quality and performance mode, and from other videos I’ve seen on YouTube it also appears to happen on PS5 at the same point.

Power cycling the console does not resolve the issue.
