App Designer error: "unable to add component. Not enough input arguments"

I created a new blank App in App Designer. When I drag the Axes component onto the UI, after a few seconds, the following error pops up:

unable to add component
matlab.ui.control.UIAxes. Component creation failed with error:
Not enough input arguments. 

In the code view, there is also a missing ‘CodeName’ property on ‘UIAxes’. How do I resolve this error?

The issue is related to missing ‘DesignTimeProperties’ on a component, which causes the code to have components with no name. 

Please check if you have a ‘DefaultAxesCreateFcn’ or ‘DefaultFigureCreateFcn’ on groot. Sometimes these are set in the "startup.m" file.

As a workaround, please follow the following steps:

1. Set breakpoint in ‘FileReader.m’ where MAT-file is loaded. 
2. Open app in App Designer.
3. When paused, query figure for any components with 'CreateFcn' and set the CreateFcn on those components back to [] using the following command: 

   get(fig, '-not', 'CreateFcn', [])

4. Delete any components with no DesignTimeProperties using the following command:

   delete(findobj(fig, '-not', '-property', 'DesignTimeProperties'))

5. Continue and save app from App Designer.
6. Reopen the app to verify app opens fine.
