Changes in Gulp notation from version 3 to 4

[Michagin]

Gulp is introduced in episode 19. However, gulp recently went from version 3 to 4 and with that, a new notation is used.
function arguments are now supposed to be used with gulp.task( 'default', gulp.series('styles', 'js'), function() { instead of an ordinary array gulp.task( 'default', ['styles', 'js'], function() {.
Converting tasks are easy, however, when I run Gulp Watch, I get this error:

[13:41:35] Starting 'watch'...
[13:41:35] Starting 'default'...
[13:41:35] Starting 'styles'...
[13:41:35] The following tasks did not complete: watch, default, styles
[13:41:35] Did you forget to signal async completion?

I tried setting the required gulp version to 3.9.1 but that gave me 9 high severity vulnerabilities when running npm install.
When fixing them using npm audit fix (and then the recommended npm audit fix --force), npm sets Gulp's decency back to 4.0.2 as of today (Marts. 4th, 2021).

Same issue here.
I have tied 5 or 6 ways to solve this.
Downgrading, altering the sources.
Running a recovery tool.
Reinstalling the software.
Reinstalling the correct version in a VM-Ware machine.
Etcetera.

I can NOT get it to work.
Help please?

Fix it in one minute:
Just follow these steps. I'm on Windows 10 and it worked perfectly for me!

In the same directory where you have package.json create a npm-shrinkwrap.json file with the following contents:

{
  "dependencies": {
    "graceful-fs": {
        "version": "4.2.2"
     }
  }
}

Run npm install, and don't worry, it will update npm-shrinkwrap.json with a bunch of content.

Run gulp to start the project.
