The error is explicit, you have a piece of code using Magento\PageBuilder\Model\Dom\Adapter\CharacterDataInterface which do not exist in your vendor.

Two possibilities :

  1. This is a class removed in this magento version and that you are still calling in custom code. solution: if that so you need to correct it.

  2. your vendor is not properly installed for this magento version.
    solution: composer install.
