Your code will fail if the directly contain any other files other than png files (even hidden files). You need to specify the file type. Try this

clc; clear; close all;
imagePath = 'C:\Users\LENOVO\Dropbox\My PC (DESKTOP-A78LL8Q)\Desktop\task\grayScale';
savePath = 'C:\Users\LENOVO\Dropbox\My PC (DESKTOP-A78LL8Q)\Desktop\task\grayScale_tiff';
fileNames = dir([imagePath '\*.png']); % specify png here
for i = 1:numel(fileNames)
    varH =fileNames(i).name;
    I= imread([imagePath '\' varH]);
    imwrite(I ,[savePath '\'  varH(1:end-4),'.tiff'],'tiff')
end

 varH =fileNames(i).name;

That variable is going to contain the file name that you are reading in, without any directory part, but including the file extension.

 imwrite(I ,[savePath '\'  varH(1:end-4),'.tiff'],'tiff')

It still has that file extension in that line, and as well you are adding on a second file extension .tiff .

 [~, basename, ~] = fileparts(varH);
 newfile = fullfile(savePath, [basename '.tiff']);
 imwrite(I, newfile, 'tiff');
