Opencart 3 Error: A theme has not been assigned to this store!

In Opencart 3, the theme is not applied, the engine itself is fresh without changes, the theme is under version 3, I set an entry for the administrator for all files (checkboxes). I work on Openserver.

Error: A theme has not been assigned to this store!

There is such an error in the logs FILE: catalog/view/theme/listore/template/information/contact.twig CODE: {{ column_left }} NOT FOUND - OPERATIONS ABORTED!

With other topics, too, column_left as an error
