Description

Since UE5.6, ControlRig.EnableAnimNodePerformanceOptimizations is enabled by default, and this appears to be causing the issue. Specifically, when the control rig’s construction event is processed, Hierarchy->ResetToDefault() is executed and the hierarchy becomes detached, but the re-linking is delayed until the PerformUpdateToDate inside ExecuteControlRig on the next tick.

Steps to Reproduce
  1. Open the repro project attached in the EPS case
  2. Start PIE
  3. Approach the mannequin in the level
    1. The animation blueprint contains two control rigs that are switched by a state machine
  4. Press Enter Key to change state machine in the animation blueprint

 

Result:

The default pose is displayed for one tick.
