Merkuro calender Sigsevs on launch

Hey guys,

I installed Merkuro Kalender on my Endeavor-OS Laptop and while it did start up not it throws a sigsev when I try to start it now.
I switched to SQLite as the akonadi backend, but I don’t know if that is the reason.

Here is the terminal output:

/usr/lib/qt/qml/org/kde/kirigami.2/private/globaltoolbar/ToolBarPageHeader.qml:32:9: QML Loader (parent or ancestor of QQuickLayoutAttached): Binding loop detected for property "maximumWidth"
fish: Job 1, 'merkuro-calendar' terminated by signal SIGSEGV (Adressbereichsfehler)

I am happy to provide more detail, if instructed what to provide and how.
