This Stack overflow post recommends pinning pinning your pydot version to 2.0.0 (pip install pydot==2.0.0). Have you tried this?
If an issue is not reproducible on colab, it would be very hard for us to debug.
The following command works on standard Google Colab notebook: keras.utils.plot_model(model,"cifar_10.png",show_shapes=True)
It does not run on the following system, producing the error below:
