Why do I receive an error regarding 'parallel.​internal.c​ustomattr.​CustomProp​Types' when running a standalone application that uses 'parpool'?

I get the following error when I try to run a compiled executable that uses 'parpool' against MATLAB Runtime:

The specified superclass 'parallel.internal.customattr.CustomPropTypes' contains a parse error,
cannot be found on MATLAB's search path, or is shadowed by another file with the same name.

First, check if your system path points to the correct version of MATLAB Runtime (that matches the MATLAB release and Update used for deployment), as explained in the following documentation:

In addition, for using Parallel Computing Toolbox functions in deployed applications, you need to pass the cluster profile. If you haven't done it previously, check the link below for ways and steps to do it:
