ImageData = imread(Result{1}(i).raw_list.z);
imwrite(ImageData , strcat("C:\Users\toto\Documents\SP4\Camera_Images\", num2str(i), '.png'), 'png');

The error message is misleading. The problem is that, surprisingly, imwrite does not yet support string arrays for the filename.
Change your double quotes to single quotes and all should be well
imwrite(ImageData , strcat('C:\Users\toto\Documents\SP4\Camera_Images\', num2str(i), '.png'), 'png');
Or rather than using strcat + num2str, use sprintf:
imwrite(ImageData , sprintf('C:\Users\toto\Documents\SP4\Camera_Images\%d.png', i), 'png');

Great!! I was going mad with this error. Thank you for saving me quite some time of headbanging on the desk.

Note that support for strings in imwrite was implemented in R2018b, so if you're using a recent version of matlab, this answer is no longer relevant.
