Still happening for me when packaging. (as of 12/23/2023 with 5.3.2)
[UPDATE]
I tried changing MetaHumanIdentity to Editor as @brandav suggested (Thank you), and that appears to have worked. I am able to package now.
Just edit .uplugin:
{
“Name”: “MetaHumanIdentity”,
“Type”: “Editor”,
“LoadingPhase”: “Default”,
“PlatformAllowList”: [
“Win64”
]
},
