The ControlRig does not seem to evaluate until you open the ControlRig asset, or if you hit compile.

Another interesting thing is if you hit compile again stops working.
This does not work for all instances either (as you can see in the video there are multiple faces)

Steps to Reproduce
  • Sync //UE5/Main
  • /Samples/Showcases/MetaHuman/MetaHumanSample.uproject
  • Open LevelSequence MetaHumanSample_Sequence
  • Go to frame 760 aprox
  • Open Face_PostProcess_AnimBP
  • Double click in ControlRig node.
