.csv file converted to 1xN char, not allowing me to use importdata()

I am very new to matlab and am having trouble using the importdata function. The program gives an error when attempting to import filename1. The workspace defines the filename as being a 1xN char instead of an NxM array -- I think the problem might be there, but I do not know how to go about fixing it. I've attached a snippet of the code and a small .csv file.

Thank you for your help.

% IMPORT DATA
filepath = pwd;
filename1 = strcat(filepath, '\type1.csv');
warning('off', 'MATLAB:table:ModifiedAndSavedVarnames');
data1 = importdata(filename1);
outputfilepath = pwd;
[~foldername] = fileparts(outputfilepath);
exptdesg = 'Folder'

"The workspace defines the filename as being a 1xN char ..."

Because that is exactly what a filename is.

"...instead of an NxM array -- I think the problem might be there"

What exactly is the problem? So far it is not clear.

Sorry, the problem is that I get an error when I try to make the data1 variable. When I call importdata(filename1) it gives an error that it is unable to open the file.

filepath = pwd;
filename1 = fullfile(filepath, 'type1.csv');
data1 = readmatrix(filename1);
