-- Information about the crash:
On a fresh installation of Fedora 42 KDE Plasma Edition, the partitionmanager crashes while it tries to read / access all available hard drives. It happens constantly as long as the USB stick - which was used to install Fedora - is plugged in. If I unplug the USB stick the partitionmanager opens as expected.

Steps to reproduce:

1. Install Fedora 42 KDE on an available system
2. Keep the USB stick plugged in after the installation
3. Try to open partitionmanager and unlock it via polkit
4. It crashes as long as the USB stick is plugged in

The crash can be reproduced every time.
