After updating to OS 13.0.0-beta1, access to installed themes is restricted by social_core Themecontroller
public function getTheme(Request $request): array {
// Get the theme.
$theme = $request->attributes->get('theme');
// If the route parameter does not contain 'socialblue'.
if ($theme !== 'socialblue') {
// Then the user has no access.
throw new AccessDeniedHttpException();
}
// The form we need.
$form = '\Drupal\system\Form\ThemeSettingsForm';
// Build the theme settings form with the extracted form and theme from the
// request.
return $this->formBuilder->getForm($form, $theme);
}
}
If you are using a custom theme, you can not edit it.
If you want to change settings on the admin theme, you cant do it.
Allow at least admininstrators to access all themes or add an api to allow to register more themes admistators have access too.

Hello slowflyer,
Thanks for the report.
We will take a look into this because as far as we know we are not trying to restrict access for our Open Source users. But likely some regression caused after we moved the theme to the distribution.
