What shows up for

which readcell

Question: do you have any third-party packages such as SPM or dfield8 or matcont installed?

I suspect that you have a third-party toolbox that is interfering with the normal operation of MATLAB.

My guess is that you are using a third-party toolbox that defines a function named isstring .

You could use

dbstop in readcell
readcell("rte_ioc_map.csv")

and then use the debugger to single step. In particular I expect you would need to "step in" on the line

C = func.validateAndExecute(filename,varargin{:})
