I am trying to simple change the logo shown on the admin login page. After creating the following files i have run
magento setup:upgrade
magento setup:static-content:deploy -f
magento setup:di:compile
magento cache:clean
app/design/adminhtml/Myvendor/mycustomadmintheme/theme.xml
<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
<title>My custom admin theme</title>
<parent>Magento/backend</parent>
</theme>
app/design/adminhtml/Myvendor/mycustomadmintheme/registration.php
<?php
MagentoFrameworkComponentComponentRegistrar::register(
MagentoFrameworkComponentComponentRegistrar::THEME,
'adminhtml/Myvendor/mycustomadmintheme',
__DIR__
);

<argument name="logo_height" xsi:type="number">85</argument> <!-- Add custom logo height -->
</arguments>
</referenceBlock>
</body>
</page>
the di.xml file in etc folder of my working module is as follows:
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<type name="MagentoThemeModelViewDesign">
<arguments>
<argument name="themes" xsi:type="array">
<item name="adminhtml" xsi:type="string">Myvendor/mycustomadmintheme</item>
</argument>
</arguments>
</type>
</config>
despite all this the logo stays the same. however when i open the logo image in new tab, i can see that the default magento logo is pulled from static/version1704465742/adminhtml/Myvendor/mycustomadmintheme/en_US/images/magento-logo.svg
So, the theme is working but the default.xml or admin_logo.xml is not. Can anyone tell me where i am going wrong, the magento version is 2.4
