Description
To reproduce this the design effects demo is required: https://git.qt.io/public-demos/qtdesign-studio/-/blob/master/examples/DesignEffectsDemo
This is a regression against Qt 6.7.2.
how to reproduce:
Run the livepreview with CalculatorDemo.ui.qml from the command line:
qmlpreview qml.exe -I "C:/Users/Thomas Hartmann/Documents/QtDesignStudio/examples/DesignEffectsDemo/imports" "C:/Users/Thomas Hartmann/Documents/QtDesignStudio/examples/DesignEffectsDemo/content/calculator/CalculatorDemo.ui.qml"

We see similar crashes with other examples, but this is the most simple one.
