Thank you in advance!

Does your Run_Script script file define a variable named path on line 1, right before it tries to call the path function on line 2? [I suspect it does.] As long as that variable exists MATLAB cannot call the path function.
Changing the name of that variable would resolve the problem, but a script file trying to reinitialize the MATLAB search path as part of its execution smells kind of bad to me. Why is your script trying to do that?

There is no variable defined as "path". Line 1 is just a %% heading.
The first line of code is:
path(pathdef)

Do you have a variable named path in your workspace when you run the script? To check use this command.
which -all path
/MATLAB/toolbox/matlab/general/path.m /MATLAB/toolbox/matlab/codetools/@mtree/mtree.m % mtree method

Yes, here is what it returns:
C:\Software\Mathworks\Matlab_All_Products_2017a\toolbox\matlab\codetools\@mtree\path.m % Shadowed mtree method
C:\Software\Mathworks\Matlab_All_Products_2017a\toolbox\driving\driving\@drivingScenario\path.m % Shadowed drivingScenario method
C:\Software\Mathworks\Matlab_All_Products_2017a\toolbox\matlab\general\path.m % Shadowed
