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.

Just a heads up, during the talent show revisit, if you hold X to fast forward, Claire's position desyncs and it prevents the other characters from walking through her and causes a softlock.
