'untitled_cgxe.mexw64' removed

I'm learning real-time audio processing with the webinar "Real-time Audio Processing for Algorithm Prototyping and Custom Measurements" (https://se.mathworks.com/videos/real-time-audio-processing-for-algorithm-prototyping-and-custom-measurements-121075.html) videos and scripts.

The scripts work well in Matlab, but when I try to run the simulink model as described in the video,

I got the following errors:

### Build procedure for model: 'untitled' aborted due to an error.
Problem creating simulation target for the model 'untitled'.
Component:Simulink | Category:Model error
Error(s) encountered while building simulation target MEX-file for model 'untitled'.
