character mesh no longer follows the animated rig (controllers)

Summary

Hello,
I animated the character in the attached video in Unreal Engine 5.6, but after reopening the project, the character mesh no longer follows the animated rig (controllers) and remains in the neutral pose. When I move the rig, the mesh snaps into a pose but still doesn’t follow the keyframed animation. Could you please advise?
Thank you.
