imagePath = 'C:\Users\images';
savePath = 'C:\Users\images_tiff';
fileNames = dir(imagePath);
fileNames = fileNames(3:end);
for i = 1:size(fileNames,1)
varH =fileNames(i).name;
I= imread([imagePath '\' varH]);
imwrite(I ,[savePath '\' varH,'.tiff'],'tiff')

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');
