The model in dots unity project cannot be rendered.

[kulame]

Hello everyone, why my fbx model can't render success in a dots project?

I refer to the project Raycast Car https://github.com/Unity-Technologies/EntityComponentSystemSamples/tree/master/PhysicsSamples/Assets/13.%20Raycast%20Car

my code is https://github.com/kulame/CarTest

When I started the project, my model suddenly disappeared, but the map model remained.
