I upgraded my website from 10.5 to 11.4.

On top of the http://localhost/admin/reports/status page, there are Error message listed like bellow:

Warning: Undefined array key "bootstrap_styles" in Drupal\locale\LocaleProjectRepository->Drupal\locale\{closure}() (line 83 of core/modules/locale/src/LocaleProjectRepository.php).

This Error message is shown at some specific pages like below:
http://localhost/admin/config
http://localhost/admin/reports/status
http://localhost/admin/reports/translations (but not shown at http://localhost/admin/reports)
 

And /admin/reports/translations page says "All translations up to date."

I have already tried drush cr.
vendor/bin/drush locale:check command can make sure the existance of things listed on the Error message.
vendor/bin/drush php:eval "print_r(\Drupal::keyValue('update_available_release')->getAll());" command returns blank array.

AI I consulted says it should be bug of Drupal.

Any advise?

After uploading the dev site to prod site, the issue disappeared.
I have no idea what happens.

I will try migrate the prod site back to dev environment and see what happens later..
