Referenced sniff "PHPCSUtils" does not exist

Question

I have PhpStorm and installed "squizlabs/php_codesniffer". When I try to use (e.g. modify the source code), PhpStorm sends me a little error every time, as

Referenced sniff "PHPCSUtils" does not exist

I tried to get that PHPCSUtils like that:

composer config allow-plugins.dealerdirect/phpcodesniffer-composer-installer true
composer require phpcsstandards/phpcsutils:"^1.0"

from here: https://phpcsutils.com/

but it then says:

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires phpcsstandards/phpcsutils ^1.0, found phpcsstandards/phpcsutils[dev-stable, dev-develop, 1.0.0-alpha1, ..., 1.x-dev (alias of dev-stable)] but it does not match your minimum-stability.

When I try composer require phpcsstandards/phpcsutils:"dev-stable" I get

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Root composer.json requires phpcsstandards/phpcsutils dev-stable -> satisfiable by phpcsstandards/phpcsutils[dev-stable].
- phpcsstandards/phpcsutils dev-stable requires squizlabs/php_codesniffer ^3.7.1 || 4.0.x-dev@dev -> satisfiable by squizlabs/php_codesniffer[3.7.1] from composer repo (https://repo.packagist.org) but squizlabs/php_codesniffer is the root package and cannot be modified. See https://getcomposer.org/dep-on-root for details and assistance.

but that's a lie, I got 3.7.1 phpcodesniffer version:

phpcs --version

PHP_CodeSniffer version 3.7.1 (stable) by Squiz (http://www.squiz.net)

my composer.json is:

{
    "require": {
        "squizlabs/php_codesniffer": "^3.7"
    }
}

the phpcs composer.json is:
