About Unreal Citysample

Here now houdini 18.5.532 seems disappear… I could’nt download it anymore

I did unreal city sample document here
( City Sample Quick Start for Generating a City and Freeway using Houdini | Unreal Engine 5.0 Documentation )

So I am doing This tutorials by 18.5.7( now I can download simmilar version )but I cant export PBC…and there are a lot of errors…

Is there someone who did it recently?
