-- Information about the crash:
After upgrading KDE Plasma to 6.3.0 from the Arch Linux repositories, I faced a very long black screen after login to my account via SDDM. Just a blinking console cursor was shown - no graphical elements. The system didn't react to any keyboard/mouse input. After several minutes, the desktop slowly appeared with a spinning notification of the akonadi_migration_agent. It does not seem to progress/finish even now after almost 20 min running. When I opened KOrganizer, I noticed that the calendar of my university's Microsoft 365 account was not fully synchronized. To resolve the issue, I tried clearing the synchronisation state (folder tree state and folder item state) via the advanced tab in the Microsoft Exchange Configuration dialog. After hitting OK, the crash was reported.

I have faced the black screen behavior after SDDM login now several times when KDE Plasma were updated with pacman to a new release. The unresponsiveness and lack of any status message for more than a minute is irritating and triggers people to force a reboot. The ACPI signals generated by the power button seem to at least trigger a clean shutdown. However, I observed at several occasions, that even the shutdown got stuck.

The reporter is unsure if this crash is reproducible.
