I ran this example on window server 2019 but it reported this error. However, this example still works a few months ago, does anybody know the reason ?

Hi,

The error you mentioned might be because you closed the Unreal Engine Simulation window before stopping the simulation in Simulink. When the Unreal Engine Simulation window is stopped before Simulink, it still tries to connect to Unreal and fails eventually. Hence, a read error is thrown. Please let me know if the issue persists in other scenarios as well. Thanks!

Hello, thank you very much for your answes. I just tried this example again and did not close any window, but still got this error. I think maybe this is not the reason.
