Magento 2, creating a theme?

Question

Magento

Created basic theme files according to the documentation. After applying a theme, many resources do not load on page load. Why? Unless, if they are absent in the theme, they should not be taken from the parent one (in this case, "Magento/blank").
php bin/magento setup:static-content:deploy - executed, cleared the cache.
"Current application mode: developer."

File structure

theme.xml

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
    <title>myTheme</title> <!-- your theme's name -->
    <parent>Magento/blank</parent> <!-- the parent theme, in case your theme inherits from an existing theme -->
    <media>
        <preview_image>media/preview.jpeg</preview_image> <!-- the path to your theme's preview image -->
    </media>
</theme>

registration.php

<?php
/**

 * See COPYING.txt for license details.
 */
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::THEME,
    'frontend/myVendor/myTheme',
    __DIR__
);

Screen/console

Thank you!

A similar issue has been discussed here.
When deploying static content, make sure that the console does not give any errors and I recommend that you always check the rights and folders of the generated files so that their owner matches the owner of the site files
