Could not connect to specified Arduino board Processor in Loop, MATLAB2018b, Simulink9.2, Arduino UNO

I am trying to recreate this example with Arduino Uno: https://www.mathworks.com/help/supportpkg/arduino/examples/code-verification-and-validation-with-pil.html#d120e3285

The S function is generated without an issue, however when I try to simulate this. I get the following error.

.......................... Error Message ...............................................

Could not connect to specified Arduino board.

Verify that the board is connected to your host, and that the host COM port number set in the model matches the COM port number in Windows.

To change the host COM port number in the model, click 'Simulation ', click 'Model Configuration Parameters'... In the dialog that opens, select the 'Hardware Implementation' pane, click 'Target hardware resources > Host-board connection' and set the COM port number.

To find out the COM port number in Windows, open Device Manager and open your board in the COM ports group.

Already tried.

Setting Com port and Baud rates manually.

Clearing all workspace variables.

Please help. Thanks and Regards

[경민 박]

I had same problem, and this is how I solved it.

In my case, I created new empty folder, and then in MATLAB I moved my Current Folder to that new empty folder.

Then, I tried PIL example again, it worked.
