poseKit is a Library that uses ARKit and RealityKit to track a body position and return the position in a json. It has more than 4 million different position possibilities
Basically, in order to circumvent this issue which occurs for all uses of BodyTrackedEntity one needs to build to Generic iOS Device or to an actual device.
It is very likely that your build destination is currently set to a Simulator, and those symbols are not available in the Simulator. You want to make sure you set the destination to either Generic iOS Device, or to an actual device.

I looked into it a little with dynamic time warping - but wonder if you have encountered this....
