gulp doesn't run the page

With some update, the gulp from new projects stopped starting. Reworked the popular answers to this question, but my build with other users is different. I haven’t climbed into the javascript yet, and as if I didn’t want to figure it out, it still doesn’t work. It is interesting that the project with which I worked before these updates works with this gulpfile. By the way, I use the preprocessor SCSS.

const autoPrefixer = require('gulp-autoprefixer');

let project_folder = "dist";
let source_folder = "#src";

let path = {
   build: {
      html: project_folder + "/",
      css: project_folder + "/css/",
      js: project_folder + "/js/",
      img: project_folder + "/img/",
      fonts: project_folder + "/fonts/",
   },
   src: {
      html: [source_folder + "/*.html", "!"+source_folder + "/_*.html"],
      css: [source_folder + "/scss/*.scss", "!"+source_folder + "/_*.scss"],
      js: source_folder + "/js/script.js",
      img: source_folder + "/img/**/*.{jpg,png,svg,gif,ico,webp}",
      fonts: source_folder + "/fonts/*.ttf",
   },
   watch: {
      html: source_folder + "/**/*.html",
      css: source_folder + "/scss/**/*.scss",
      js: source_folder + "/js/**/*.js",
      img: source_folder + "/img/**/*.{jpg,png,svg,gif,ico,webp}"
   },
   clean: "./" + project_folder + "/"
}

Thank you all for your answer, because I really spent a lot of time and nerves on it)
