Built in function cd not being found when running a custom function

Hello, I am having an issue where cd is not being found when I run a custom script. The relevant script is as follows, [tmp] being a placeholder that removes identifying information. cvfn is the name of a file that is located in basepath.
function horm_symptom(cvfn)

close all;

basepath={‘C:\Users\[tmp]_WorkingFolder’;
‘C:\Users\[tmp]_WorkingFolder’};

if exist(basepath{1},’dir’), basepath=basepath{1};
elseif exist(basepath{2},’dir’), basepath=basepath{2};
else, error(‘basepath does not exist’);
end

addpath(genpath(basepath));

savepath=fullfile(basepath,’SingleSubjectData’);
if ~exist(savepath,’dir’), mkdir(savepath); end
cd(‘SingleSubjectData’);

When i run the script I get the following error at the line cd(‘SingleSubjectData’)
Unrecognized function or variable ‘cd’.
However, if I set a breakpoint at ‘cd(‘SingleSubjectData’);’ and type the following, I get:
exist(‘cd’,’builtin’)

ans =
5

which(‘cd’)

ans =
built-in (C:Program FilesMATLABR2023btoolboxmatlabgeneralcd)
I’ve also successfully used addpath to the above directory with no errors, but even still I get the unrecognized function error.
addpath(‘C:Program FilesMATLABR2023btoolboxmatlabgeneral’)

I’ve tried different formats for cd, including adding and removing parentheses, semi-colons, and tildes and nothing has worked.
If I set a break point and type the following directly into the command window it works and changes directory,
cd ‘SingleSubjectData’
However, if I try to run the code with the above formatting within the script I get the following error:
horm_symptom(cvfn)

Error: File: horm_symptom.m Line: 21 Column: 1
Using identifier ‘cd’ as both a variable and a command is not supported. For more information, see "How MATLAB
Recognizes Command Syntax".
The above error occurs when I try any of the following formats:
cd SingleSubjectData;
cd SingleSubjectData
cd ‘SingleSubjectData’
cd ‘SingleSubjectData’;
cd ~/SingleSubjectData

I have checked that a variable named "cd" is not getting created, confirmed that the sub folder SingleSubjectData is getting created and does exist and reviewed the How Matlab recognizes command syntax page linked in the error. I am at a loss of how to fix this or whats wrong. Lastly, I know I’m talking about SingleSubjectData, but I have also tried cding into savepath, and have had all the same errors described above.
