I have this code:

async function checknamedirect(arg) {
    let check = await arg.startsWith('YT')
    if (check) {
        return true
    }
}

async function checkitems(limit, check, second_limit, megaitem, new_item, check_years, years, check_views, views) {
    let result = await Number(limit) <= Number(check) && Number(check) <= Number(second_limit) &&  megaitem == 'Y' + new_item && check_years <= years && check_views >= views
    if (result) {
        return true
    } else {
        return false
    }
}

getFiles('./folder/', function (err, files) { 
    fs.mkdir('result/' + limit[1] + ' do ' + second_limit[1], err => {
        console.log('Folder: '.green + limit[1] + ' do ' + second_limit[1] + ' was created');
    });
    fs.mkdir('result/' + limit[1] + ' do ' + second_limit[1] + '/Brand', err => {
        console.log('Folder: '.green + 'Brand was created');
    });
    fs.mkdir('result/' + limit[1] + ' do ' + second_limit[1] + '/NoBrand', err => {
        console.log('Folder:'.green +' NoBrand was created');
    });
    for (const megaitem of getDirectories('./folder/')) {
        if (checknamedirect(megaitem)) {
            for (const item of files) {
                let direct = path.dirname(item)
                const array = fs.readFileSync(item).toString().split("\n");
                for (const item of array) {
                    let check = item.match(/Account (.+) Subs: (\d+)/)
                    let check_years = item.match(/Created: .+\/.+\/(\d+)/)
                    let check_monet = item.match(/Monetized: (.+) Created/)

                        let new_item = direct.match(/Y(.+)/)
                        checkitems(limit[1], check[2], second_limit[1], megaitem, new_item[1], check_years[1], years[1], check_views[1], views[1]).then( data => {
                            if (data) {
                                if (findWord('Brand', item)) {
                                    fska.copy('./folder/' + megaitem, './result/' + limit[1] + ' do ' + second_limit[1] + '/Brand/' + check_years[1] + '(Y) ' + check[2] + '(S) ' + check_monet[1] + '(M) '  + check_views[1] + '(V)' , err => {

                                    });
                                } else {
                                    fska.copy('./folder/' + megaitem, './result/' + limit[1] + ' do ' + second_limit[1] + '/NoBrand/' + check_years[1] + '(Y) ' + check[2] + '(S) ' + check_monet[1] + '(M) '  + check_views[1] + '(V)' , err => {

                                    });
                                }
                            }
                        })
                    }
                }
            }
        }
    }
});

The first time I encounter such an error, I don’t understand why it happened, but it appeared after async / await in the code, maybe I’m using it wrong, how to fix it?
