Error using rmdir baseDir, 's' is not a directory

I've used this code many times before but recently messed with my tmp folder when I was trying to use VBA in Excel on my Mac and now I am getting this error:

|Warning: The following error was caught while executing 'onCleanup' class destructor:

Below is my code:

%For 96 well or 384 well plates
clc 
clear all

%need to enter file name as string in purple
filename='180629 Plate Reader.xlsx';
tp=30; %time point interval, in minutes
tph=tp/60; %convert to hrs
%Read data
[data,rowLabel]=xlsread(filename);
tpn=0; %Initialize: number of time points in data set
rows=0; %Initialize: rows on plate
for i=1:length(rowLabel)
    if strcmp(rowLabel(i),'<>')
        tpn = tpn+1;
        rows = 0;
    else
        rows=rows+1;
    end
end
[~,columns]=size(data);
%plate details
if rows==8
    platetype='96 well';
    [~,wellnames]=xlsread('welllabels','96well');
else if rows==16
    platetype='384 well';
    [~,wellnames]=xlsread('welllabels','384well');
else
    platetype='unknown'; 
    end
end
headers=0; %there are headers with column labels in data
sampledata=[];
samplerow=0;
colcount=0;
for j=1:length(rowLabel) %Go through every row in data
    if (j==1) || (j==rows*(headers)+(headers+1)) 
        headers=headers+1;
        colcount=1; %Reset the column count after each header
    else
        samplerow=ceil((j-headers)/rows); %Corresponds to timepoint for that row
        sampledata(samplerow,((colcount*columns-columns+1):colcount*columns))=data(j,:);
        colcount=colcount+1;
    end
end

%Add labels
time=0:tph:tpn*tph; %Time point labels
datatowrite(1,2:length(wellnames)+1) = wellnames';
datatowrite(2:length(time)+1,1) = num2cell(time');
datatowrite(2:length(sampledata(:,1))+1,2:length(sampledata(1,:))+1) = num2cell(sampledata);

% Removes the extension from filename
t = findstr(filename,'xlsx');
filename = filename(1:t-2);
%Write to file   
xlwrite(['Formatted ' filename '.xlsx'], datatowrite)

What did you change using VBA? I suspect that this can't be fixed from the MATLAB end, you will need to get Excel back to the way it was.
