KDE partitionmanager does not recognize partition table

Hi,
KDE Partition Manager does not recognize the partition table of a specific usb stick.

lsblk -f

NAME        FSTYPE  FSVER            LABEL       UUID                                 FSAVAIL FSUSE% MOUNTPOINTS
...
...                                                                                     
sdb                                                                                                  
├─sdb1      exfat   1.0              Ventoy      D074-E105                                           
└─sdb2      vfat    FAT16            VTOYEFI     3925-9DE7                                           
...
...

I can mount both partitions without problem.

when I start partitionmanager (LC_ALL=C partitionmanager) in the terminal, this is the output:

Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.

When I use partitionmanager in my fedora live environment, it works fine.
I appreciate any hint, thanks!

Re: KDE partitionmanager does not recognize partition table

I just noticed that KDE Partition Manager (KPM) does not recognize DOS partition tables, but only GPT.
In the GUI it shows the disk without any partition inside it, while Gparted shows all the partitions correctly.

Starting KPM from a terminal, it says:

...
unknown file system type  "dos"  on  "/dev/sda"
...
unknown file system type  "dos"  on  "/dev/sdb"

sda and sdb are my root and home respectively.

Same thing when inserting a USB stick with a DOS partition table.

When using an external USB disk with a GPT partition table, it says "Scan complete" (or something, I use another language than English).

Clearly, all these devices (DOS and GPT) work perfectly.
