library compiler for Excel Add-in error with packaging

I'm using matlab compiler app to create an Excel add in I follow the instructions as in

https://www.mathworks.com/help/compiler/excel/create-an-excel-application-from-matlab-code.html

The packaging process stops in the middle with an error and creates the log file below.

Does anyone know why am I getting this LiveEditorEvaluationHelper file?

Are you trying to include a .mlx Live Editor file ?

[Ameen Muhammed]

I'm not.

I'm only including one function that runs an enhanced fft analysis

I'm using the App interface with the input below

I do not know why that is being used, but if the .mlx file still exists, then try deleting it.
