Drupal 10 compatibility issue with older sub theme

Hello,

If you don't have any custom javascript using jquery.once library in the sub-theme or a custom page.twig.tpl you just need to upgrade the main theme from 8.x-1.21 to 2.0.11 and it should be enough.

If you have a custom code in page.twig copy the custom code to the new page.twig from 2.0 and add it to the sub-theme.
If you have any custom js code in the sub-theme, you will have to update it. https://drupalbook.org/blog/replace-jqueryonce-javascript-once-drupal-10

Best wishes,
