Using the shipped 'vdynblksDblLaneChangeStart' demo with the '3D Engine' visualization turned on, the model errors with the following message upon simulation:
MATLAB System block 'DLCReferenceApplication/Visualization/3D Engine/3D Engine/Simulation 3D Engine 1/Simulation 3D Engine' error occurred when invoking 'setupImpl' method of 'Simulation3DEngine'. The error was thrown from:
'C:\Program Files\MATLAB\R2018b\toolbox\shared\sim3d\sim3d\+sim3d\Engine.p' at line 0
'C:\Program Files\MATLAB\R2018b\toolbox\shared\sim3d\sim3d\+sim3d\Engine.p' at line 0
'C:\Program Files\MATLAB\R2018b\toolbox\shared\sim3d\sim3d\+sim3d\Project.p' at line 0
'C:\Program Files\MATLAB\R2018b\toolbox\shared\sim3dblks\sim3dblks\Simulation3DEngine.p' at line 0'.
Caused by:
Invalid default value for property 'engine' in class 'sim3d.Engine':
3D simulation engine interface setup error (1). Please check the toolbox preferences and ini-file.
Is there a way to fix this?

This issue is potentially caused by spaces in the Windows "%temp%" directory path. Once your Windows "%temp%" directory path does not have a space, the simulation should be able to execute without error. Spaces in the Windows "%temp%" directory may be caused by spaces in the Windows username.

As noted in some of the answers above, this issue is related to a Windows update that changed a part of the .NET infrastructure that our interface to Unreal was relying on. Subsequent updates to our product have fixed the interface, so updating MATLAB should fix this issue. You can read more here.
