3D simulation engine interface setup timeout.

I am getting this error when i try to run the script in this example Visualize Automated Parking Valet Using Unreal Engine Simulation.

MATLAB System block 'untitled/Simulation 3D Scene Configuration/Simulation 3D Engine' error occurred when invoking 'resetImpl' method of 'Simulation3DEngine'. The error was thrown from '
 'C:\MATLAB2020b\toolbox\shared\sim3d\sim3d\+sim3d\EngineInterface.p' at line 0
 'C:\MATLAB2020b\toolbox\shared\sim3d\sim3d\+sim3d\Engine.p' at line 0

 'C:\MATLAB2020b\toolbox\shared\sim3dblks\sim3dblks\Simulation3DEngine.p' at line 0'.
Caused by:
3D simulation engine interface setup timeout.

Can anyone help me fix this ?

Please make sure that Unreal Engine is installed on your computer. See the system requirements:

Hi Ahmed, this error could be due to not clicking 'Start' on UE to start simulation when doing co-simulation with the Unreal Editor.

If you don't click 'Start' for some time, Simulink will throw this error.
