The error message is the following:

Error using matlab.internal.imagesci.pngwritec
PNG library failed: Write Error.
Error in writepng (line 316)
matlab.internal.imagesci.pngwritec(data, map, filename, colortype, bitdepth, ...
    
Error in imwrite (line 566)
feval(fmt_s.write, data, map, filename, paramPairs{:});
Error in Videos_guapos_orden_4>generate_image (line 332)
imwrite(imind,map,fulldestination);
Error in Videos_guapos_orden_4 (line 124)
generate_image(x,z,tstep,u2,A,fig,destdirectory);

And the generate_image function is

function generate_image(x,z,tstep,u2,A,fig,destdirectory)
    imagen = [flip(u2(3:end-3,:)); u2(3:end-2,:); flip(u2(4:end-3,:)); u2(3:end-2,:); flip(u2(4:end-3,:)); u2(3:end-2,:)];
    imagesc(x,z,imagen, [0 A^2]);        % draw image and scale colormap to values range
    colorbar; % set colorbar
    set(gca,'FontSize',20)
    Z = length(z)-1;
    yticks([0 z(floor(Z/6)) z(floor(Z/3)) z(floor(Z/2)) z(floor(2*Z/3)) z(floor(5*Z/6)) z(Z)])
    yticklabels({'-3/2 d','- d','-1/2 d','0','1/2 d','d','3/2 d'})
    
    X = length(x)-1;
    xticks([x(1) x(floor(X/4)) x(floor(X/2)) x(floor(3*X/4)) x(X)])
    xticklabels({'0','1/4 Z_T','1/2 Z_T','3/4 Z_T','Z_T'})
    drawnow
    frame = getframe(fig);
    im = frame2im(frame);
    [imind,map] = rgb2ind(im,256);
    thisimage = ['img_',num2str(tstep),'.png'];
    fulldestination = fullfile(destdirectory,thisimage);
    imwrite(imind,map,fulldestination); % The error occurs HERE
end
