Gulp not creating css folder when using plugin?

Question

gulp.js

let project_folder = require ("path").basename(__dirname);
let source_folder="#src";
let fs = require('fs');


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/style.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 + "/"
}

let{ src, dest } = require('gulp'),
    gulp = require('gulp'),
    browsersync = require("browser-sync").create(),
    fileinclude = require("gulp-file-include"),
    del = require("del"),
    scss = require('gulp-sass')(require('sass')),
    autoprefixer = require("gulp-autoprefixer"),
    group_media = require("gulp-group-css-media-queries"),
    clean_css = require("gulp-clean-css"),
    rename = require("gulp-rename"),
    uglify = require("gulp-uglify-es").default,
    svgsprite = require("gulp-svg-sprite"),
    ttf2woff = require("gulp-ttf2woff"),
    ttf2woff2 = require('gulp-ttf2woff2'); //Шрифты
    const imagemin = require('gulp-imagemin');
    

     

    
    
    
    



    function browserSync (params) {
    browsersync.init({
        server:{
            baseDir:"./" + project_folder + "/"

        },
        port: 3000,
        notify:false
    })
}

function html() {
    return src(path.src.html)
        .pipe(fileinclude())
        .pipe(dest(path.build.html))
        .pipe(browsersync.stream())
}

function css() {
    return src(path.src.css)
    .pipe(
        scss({ outputStyle: 'expanded' }).on('error', scss.logError)
    )
    .pipe(
        group_media()
    )
        .pipe(
        autoprefixer({
            overrideBrowserslist:["last 5 versions"],
            cascade:true
        })
    )
    .pipe(dest(path.build.css))
    .pipe(clean_css())
    
    .pipe(
        rename({
            extname:".min.css"
        })
    )
   

    .pipe(dest(path.build.css))
    .pipe(browsersync.stream())
    
}


let build = gulp.series(clean, gulp.parallel(js, css, html, images, fonts ),fontsStyle);
let watch = gulp.parallel(build, watchFiles, browserSync);


exports.fontsStyle = fontsStyle;
exports.fonts = fonts;
exports.images = images;
exports.js = js;
exports.css = css;
exports.html = html;
exports.build = build;
exports.watch = watch;
exports.default = watch;

I think the problem is in the plugin scss = require('gulp-sass')(require('sass')).
