Control Rig delayed by a frame in sequence

I think this is a new issue since updating to 5.4. But my sequences with a keyframed control rig seem to be having an issue. When playing the sequence, the control rig isn’t taking affect right away. So the first frame is a flash of the character t-posing. It doesn’t happen all the time, so I think there’s some sort of order-of-spawning thing going on? Is anyone else seeing this issue?
