Cannot Import 3D City Model using Unreal SDK 2.2.1

[saji8k]

Sorry for using English, I can't write in Japanese well.

I am unable to load a mesh using the Unreal SDK. I have tried both local import and server import and they both cause the editor to crash.

OS: MacOS 14.5 ARM
Unreal: Unreal 5.3.2
Plateau: PLATEAU SDK for Unreal v2.2.1

Steps to reproduce:
Started with blank project
Then followed the steps in https://project-plateau.github.io/PLATEAU-SDK-for-Unreal/manual/ImportCityModels.html to load from server.
Selected one mesh code area (Shibuya: 53393596)
Plugin starts importing, then the editor crashes with the following output.

@saji8k
We apologize for the inconvenience regarding PLATEAU SDK for Unreal.
Currently, there is a bug that causes Unreal Engine to crash when importing 地下街(underground structures). We are currently working on addressing this issue. As a workaround, you can import other city types by unchecking the "インポートする"(Import) option for 地下街(underground structures).
