hi @Reeyawn ,
You can only import assets using
Converting Assets into Props in Unreal Editor for Fortnite | Unreal Editor for Fortnite Documentation | Epic Developer Community
or
Importing Assets in Unreal Editor for Fortnite | Unreal Editor for Fortnite Documentation | Epic Developer Community
If you try and import from a Migrated Asset in UE5 5.* engine
everything is disallowed in UEFN/Fortnite
UE5 PYTHON Is not supported in UEFN as this is a subset of the Enginr
Disallowed is for anything not imported in Fortnight
