Slideshow on calamares installer show white blank

During the installation process using the KDE neon Calamares installer, the slideshow intended to showcase KDE neon branding and information fails to load. Instead of displaying the expected content, a white blank screen is shown.  

STEPS TO REPRODUCE:  
1. Boot the KDE neon ISO image.  
2. Launch the installer using Calamares.  
3. Observe the slideshow section during the installation process.  

EXPECTED BEHAVIOR: 
The slideshow should display informative slides with appropriate text and images, highlighting KDE neon features.  

ACTUAL BEHAVIOR:  
The slideshow remains blank, showing a white screen instead of the intended content.  

DEBUG INFORMATION  
Relevant debug output from Calamares:  

```
12:08:37 [2]: void Calamares::SlideshowQML::loadQmlV2Complete()
    WARNING: QML component not ready: QList(file:///usr/share/ubiquity-slideshow/slides/index.qml:48:5: Type UbiquitySlide unavailable

        ^, file:///usr/share/ubiquity-slideshow/slides/UbiquitySlide.qml:27:1: module "org.kde.neon.calamares.slideshow.context" is not installed

    import QtQuick.XmlListModel 2.0
    ^)
```  

From the debug log, it appears the following QML modules are missing:  
- `org.kde.neon.calamares.slideshow.context`  
- `QtQuick.XmlListModel`  

ADDITIONAL NOTES  
- The issue occurs consistently across installations using the same ISO image.  
- It seems the missing QML modules are critical for the slideshow functionality.  

Could you please verify if this is a known issue or if additional dependencies need to be added to the installer?  

Thank you for addressing this issue. Let me know if you require further testing or information.
