MetaHuman Manager not detecting MetaHumans in UE 5.7

I’m currently experiencing an issue with MetaHuman Manager in Unreal Engine 5.7.

When opening MetaHuman Manager, it does not detect any existing MetaHumans in the project. The window appears empty and no content is listed, even when:

  • The project contains a fully functional MetaHuman

  • The MetaHuman is properly compiled

  • All required plugins are enabled

  • The project was freshly created and tested again

I also tested migrating a working MetaHuman from another project, but MetaHuman Manager still does not detect it.

Is this a known issue in UE 5.7?
Are there any additional setup steps required for MetaHuman Manager to recognize existing MetaHumans?
