That's weird. I can't see anywhere in her pathing that could get her stuck in that spot. Any chance you saw what she got stuck against that desynced her?
From what I saw, Claire skipped a step in her pathing when she went to perform, and stood next to Janet when she did her magic instead of where she was meant to. The cutscene proceeded as normal otherwise until Annie was meant to take the stage and collided with her, leaving her unable to finish her movement script.
