Problem/Motivation
When I click on the "Manage Layout" button from a content type's "Manage Display" page (similar to /admin/structure/types/manage/content_type_machine_name/display/default), I get the following error:
Drupal\Component\Plugin\Exception\ContextException: The entity context is not a valid context. in Drupal\layout_builder\Plugin\SectionStorage\SectionStorageBase->getContextDefinition() (line 150 of core/lib/Drupal/Core/Plugin/ContextAwarePluginTrait.php).

This is after I set the "Default layout section" to a value ("One column", in my case).
Steps to reproduce
This was tested on a relatively fresh Drupal 10.2.3 site on a content type that wasn't previously using Layout Builder until I installed LB Plus.
So, to reproduce, on a content type, select the "Use Layout Builder" and "Allow each content item to have its layout customized." buttons, save the form, then set the "Default layout section" to anything, then click "Manage display".
