Control Rig for Metahuman is not manipulating MH mesh?

As I was animating my Metahuman Control Rig in sequencer, the rig suddenly ‘disconnected’ from the mesh and now the mesh is not moving at all (including other shots that I previously animated). It looks like my animation curves are preserved, but how do I ‘reattach’ the mesh?? Deleting the MH blueprint and bringing in another into the level doesn’t seem to work - the control’s move independently of the mesh. I also tried deleting my Metahuman from my project entirely and re-migrating it into the main project, no dice. Making a blank level and and level sequence, then readding my MH does not seem to make the Control Rig work. I don’t think I pressed any buttons or created anything, it simply stopped working when I was animating inside the Control Rig/Sequencer and graph editor. I did have an animation constraint on an IK hand. Could this have broken my project entirely?

did you manage to figure this out? i’ve just opened my project and something similar has happened
