Imagemin not Optimazing images in Gupl v5

[madjacky]

after updating gulp to version 5 whne i start gulp console show gulp-imagemin: Minified 1 image (saved 119 kB - 48.2%) but when i check image sizes in src & dist folders sizes are still same

const images = () => {
  return src([`${paths.imagesFolder.src}/**/**.{jpg,jpeg,png,svg}`], { encoding: false })
    .pipe(gulpif(isProd, imagemin([
      mozjpeg({
        quality: 60,
        progressive: true
      }),
      optipng({
        optimizationLevel: 2
      }),
    ])))
    .pipe(dest(paths.imagesFolder.dist))
}
