"A required background service is not operational" - Akonadi/Kontact/KMail

I recently upgraded to Fedora 44 and part of the upgrade includes KDE Gear 26.04.0 and Kontact apps getting upgraded to 6.7.0. Following this update, I am unable to interact with any Akonadi-based apps. I get an error saying “A required background service is not operational”. If I click the “Details…” button, nothing appears. Running akonadiconsole in terminal, I see the following output:

Please register the custom scheme 'cid' via QWebEngineUrlScheme::registerScheme() before installing the custom scheme handler.
org.kde.pim.akonadicore: ""
org.kde.pim.akonadicore: Job error:  "" for collection: QList()

How can I get Akonadi stuff to start working again?

Apparently the solution I found in other forum is to get rid of stuff related to the Notes module of Akonadi. Perhaps it was deprecated?
sudo dnf remove knotes akonadi-notes
and then rebooting solved the issue.
