Hi the machine has openSUSE:tumbleweed:20240418 with plasma 6.0.4 and QT 6.7.0 installed.

Previously I was able to unlock the LUKS encrypted usb drives partition by clicking on Disks & Devices in system tray and entering the LUKS passphrase. I am no longer able to do so on this machine. When clicking on the usb device I receive the message (you are not authorized to mount this device).
-
When using Dolphin to attempt to access the encrypted usb's volume - the
following error is displayed:

An error occurred while accessing '1.9 GiB Encrypted Drive', the system
responded: An unspecified error has occurred: Object does not exist at
path “/” 
-
# cryptsetup luksOpen /dev/sdb ARBITRARY_NAME
and entering the LUKS partitions passphrase does unlock the volume. 

Gparted recognizes the drive and is able to unencrypt the volume (when the passphrase is entered). 

Then I am able to access the encrypted volume by
using Dolphin after providing the root password. Dolphin has not asked
for root password before when performing this operation.

It seems as if something with how Plasma 6 uses luksOpen has broken.

Do you know what is going on here?
