Running gulp tasks in sequence throws `Unhandled stream error in pipe`

I have a gulp task as following :

gulp.task('build-files, function(cb) {
    runSequence('run-build-cmd',
        'delete-dest', 'copy-files',
        cb);
});

This task is running whenever something changed in a source folder as following :

gulp.watch(pathToSrcFolder, ['build-files']);

So this task runs 3 other gulp tasks in the specified order, the first one it runs a build command, the second one will delete a folder as following :

gulp.task('delete-dest', (cb) => {
    del([pathToDestFolder], {force: true});
    cb();
});

and the third one will copy files from a source into two destinations :

gulp.task('copy-files', () => {
    return gulp.src(pathToSrcFolder)
        .pipe(gulp.dest(pathToDestFolder))
        .pipe(gulp.dest(anotherPath));
});

Please notice that the pathToDestFolder is the same folder in both delete-source and copy-files commands.

The problem I had running this sequence, is this error:

internal/streams/legacy.js:59
      throw er; // Unhandled stream error in pipe.
      ^

Error: ENOENT: no such file or directory, chmod 'pathToDestFolder\path\to\some\file\file.ext'

I don't know why I'm getting this error.

And when I run the gulp delete-dest in cmd prompt (which will clear the pathToDestFolder) and then gulp copy-files (which will copy the source folder into two folders pathToDestFolder and anotherPath) it works as expected .

So I guess runSequence didn't work as expected ? if so, how can I solve this ?

Edit:

I tried to use rimraf instead of del, and all seems to work just fine, I know that rimraf is depricated, and it's better to use del instead, but why del in this case results in an exception ?

Edit 2:

Instead of using rimraf as a solution, I tried this solution:

gulp.task('delete-dest', (cb) => {
    del([pathToDestFolder], {force: true})
    .then(paths => {cb();});
});

And it worked like magic.

Why this worked instead ? I don't know !

If someone can clarify things I would be greatful.
