City sample in houdini can't process and export

When I run RuleProcessor_Freeway, I keep getting an error

Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 920] Attempted to create a package with name containing double slashes. PackageName: /Game/City//GEOMETRY/SM_Freeway_deck_collision_00_30

If I run the processor without decals, visible road geometry and collisions, the barriers and retaining pillars are created without any problems.

Does anyone know how to fix this and load road geometry and decals?
