I was having the same problem in UE 5.3, exporting a MetaHuman into a new blank project. The way I fixed this was to enable the plugins that looked to be required by MetaHuman before attempting to migrate. I checked which ones were needed by creating two new projects - one a Blank Film/Video & Live Events project and the other a Blank Film/Video & Live Events project with the Ada MetaHuman imported though Quixel Bridge - and then compared their plugin lists.
The ones I needed to enable were:
- Deformer Graph
- Live Link Control Rig
- RigLogic Plugin
- Groom
- Compute Framework
Unreal asked to reboot after enabling each one (which I did) and by the time I got to the Compute Framework, it was already enabled. After that, migrating the MetaHuman worked.
