Simulated citizen action interrupted and MCC error reported

I have installed many functional modules, so I don't know where the problem lies. This is the report given to me by MCC. I hope professional players can help analyze it. Thank you.

The specific scenario is to simulate a citizen picking up a CC book from the ground, preparing to put it back on the bookshelf, but suddenly interrupted and an error message pops up This is really frustrating

The last module call: __init__. py

Last activity call: get-joint_transform_from_rig

Error message: Exception in Sim Timeline: Exception running element (KeyError: 'get-joint_transform_from_rig: Union name [(null)] JointNameHash [0x888130b1] ().'), Category ID: __init__: 247
