Screenshot of error message in KDE Partition Manager
DESCRIPTION
Error message appears in desktop mode regarding Micro SD card when launching
KDE Partition Manager
STEPS TO REPRODUCE
1. Install a micro SD card and format in gaming mode upon initial
setup/unboxing of steam deck
2. Eject and change micro SD cards at some point to a different card, format
for the deck in gaming mode
3. Switch to Desktop mode, launch KDE Partition Manager and despite the card
"working" for file storage, etc., in desktop mode, an error appears stating
"unrecognized device"
OBSERVED RESULT
This issue persists and appears seemingly after changing away from the initial
Micro SD card used, despite trying many different cards it persists - attempts
have been made to format the cards on Windows, Mac, etc. - many variations but
after reformatting with the Steam Deck, KDE always says "unrecognized device".
The card appears to work normally for file access but the error persists.
EXPECTED RESULT
No error should appear and the card's partition headers/information should be
read appropriately

Windows PC, cleaning the card in PowerShell on Windows and then reformatting,
using Konsole commands to format the card on Steam Desktop mode, etc. - the
message actually displayed in the top of the popup window is: "Error While
