Modular Control Rig doesn't work in packaged builds

I’m currently working on the UE 5.5.4 but modular control rigs still don’t work.

I’ve also checked if there is a difference between regular control rigs and modular by creating simple sequence anims and then packaging it. There is a difference: the non-modular rig DO work in the packaged build (at least dev config), but the modular doesn’t.

Does anybody know if any support / fix for this coming in the nearest engine releases?
