It looks like there's a bug with QtMultimedia and how it handles gstreamer.

If you delete the import QtMultimedia 5.4 and property Audio sfx: Audio {} lines in NotificationManager.qml it should startup.

https://github.com/Zren/plasma-applet-eventcalendar/blob/master/package/contents/ui/NotificationManager.qml

I wish the plasma freedesktop notification system supported sound effects so I didn't have to manage it myself...

There's also a QtMultimedia import in the TimerView.qml and the "Events" config tab.

I can confirm this occurs on KDE neon (in the form of Feren OS Next) too after the latest gstreamer updates there:
https://bugs.kde.org/show_bug.cgi?id=410620

It only appears to occur with Event Calendar being active - all other applets I've tried don't have any issues

I probably have the same, after adding widget and and logging back in I see desktop for few seconds then it crushes to black screen with cursor. Needed to remove it from plasma-org.kde.plasma.desktop-appletsrc by hand

I've tried to wrap it in Qt.createQmlObject("import QtMultimedia 5.4; Audio {}", notificationManager) but I'm not certain if that commit in git master will fix it. Latte Dock + Event Calendar doesn't seem to crash for me in Manjaro. I'll try downloading a Neon LiveCD and trying it in a VM.

I can't reproduce the bug with the version on KDE Store and Qt 5.13.1. Could it be a Qt bug that has been fixed?

One of the updates to Qt or gstreamer probably fixed it. It's likely a Qt update. Initializing a Sound instance shouldn't of crashed the Qt "App".

Remove "notifications" dataengine to support Latte Dock (Issue #60)
5d5da6d 
We also remove the QtMultimedia sfx that caused issues in (Issue #84).

We now use notification.py for events. I've done my best to sanitize
the event summary + body.

I also made the <br> self-closing <br /> in UpcomingEvents formatting.
