For people who might run into this. During upgrade from 10.3 to 11, I ran into this error at the last stage upgrading Drupal 10.3 site to Drupal 11.4.4.
As I tried to run ddev drush updp -y. It ended with error:
> [notice] Update started: search_update_11401
> [error] Invalid data type in config views.argument_default.schema, found in file core/modules/views/config/schema/views.argument_default.schema.yml: Duplicate key "views.argument_default.date" detected at line 12.

[error] Update aborted by: search_update_11401, views_update_11201
[error] Finished performing updates.
Failed to run drush updb -y: exit status 1
Initially I was not sure which to delete, as there are 5 views.argument_default related declarations. When I asked which of the 5 to delete, Google gemini could not help; rather provided links for me to read around the topic.
Inspecting the error, I noticed this line
Invalid data type in config views.argument_default.schema, found in file core/modules/views/config/schema/views.argument_default.schema.yml: Duplicate key "views.argument_default.date" detected at line 12.
Line 12 of core/modules/views/config/schema/views.argument_default.schema.yml begins this declaration:
views.argument_default.date:
type: boolean
label: 'Current date'
once that declaration is deleted and file saved, the updp utility completed successfully.
Hope this helps someone.
