Animation Sequencer and Control Rig doesn't work in UE 5.1

Hi folks. I’m animating a character in sequencer. I added an animation and then baked it to control rig, however, when the baking is done, the character goes into A-pose and doesn’t do anything.
Does anyone know what happen?

First, we want to ensure this is what you meant. Are you placing an animation in a level and baking it to the sequencer under the control rig?

If this is the case, I have to ask if you have applied/set up the “Backward Solve” inside your control rig. It sounds like you didn’t set it up am I correct?

yes, “backward Solve” is applied

Did you see any controllers on your rig when placing in a level? Your controller might be set to hide inside your animation window tab.

Again, without the visuals, we can’t really help you much other than guessing the possibilities one by one.

Thank for ask. I finally I was able to get the control rig working, and I did the animation in sequencer, but I have another problem that I have updated in this post:
