While further details aren’t provided, it could be assumed that the Steadicam rig that was holding the camera was broken.
In line with the official Knives Out Twitter’s personal brand, those behind the page retweeted this footage and ratted out Rian Johnson for breaking the Steadicam during the filming of this particular scene.
From that point, the production was forced to proceed in capturing the rest of the shot by removing the camera itself, as you can see at roughly 00:12, where the rocking motion indicates the camera is being unhooked without cutting the take.
