Why am I unable to launch the Python executable that was created on a CTF from MATLAB Complier SDK?

I have an application in Python that uses MATLAB functions created from MATLAB Complier SDK that is running without issue. 

However, when I attempt to compile this application using PyInstaller, I am unable to run the executable created by PyInstaller as I receive the following error message:

File "C:\MATLAB\R2020a\toolbox\compiler_sdk\pysdk_py\matlab_pysdk\runtime\deployablepackage.py", line 33, in initialize
mcr_handle = self.__cppext_handle.startMatlabRuntimeInstance(self.__ctf_path)
SystemError: Cannot find CTF archive 'AppData\Local\...\[LibraryName]\[LibraryName].ctf'.

What does this error mean, and how can I fix this issue?

By default, PyInstaller will not include the CTF file in the executable that it creates. To resolve this issue, you must create a SPEC file to instruct PyInstaller to include your CTF.

For an explanation of how to do this, please see the following MATLAB Answers post which gives an example of how to create a SPEC file for this purpose.

Additionally, PyInstaller has some documentation about SPEC files that may help resolve this error.
