SUMMARY
***
After login to plasma desktop the background picture, mouse cursor and x-console shows (lists some bluez errors) but nothing else.
Eventually the rest of the desktop loads.
In system journal are multiple messages such as:
kf.solid.backends.udisks2: Error getting props: "org.freedesktop.DBus.Error.NoReply" "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." for "/org/freedesktop/UDisks2/block_devices/nvme1n1p1"

Same delay & udisks2 errors occur when opening Dolphin and Kate with the same errors when I run through gdb.
***


STEPS TO REPRODUCE
1. Login to user account


OBSERVED RESULT
Desktop wallpaper, cursor (can move but no response to clicks) and xconsole window in bottom left corner show.
No icons or task bar.
After delay taskbar & desktop icons show and desktop is usable.

EXPECTED RESULT
No delay after account login for full desktop to show and Dolphin to open immediately.

SOFTWARE/OS VERSIONS
openSuse Tumbleweed 20231001
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.110.0
Qt Version: 5.15.10
Kernel version 6.5.4-1-default (64 bit)
Graphics Platform X11

ADDITIONAL INFORMATION
Previous versions of plasma did not experience this timeout delay.

nvme1n1p1 is an ntfs partition that is set as noauto in fstab.
The partition is used by a windows 11 virtual machine which can access the device with no issue. The windows 11 vm guest is manually started so is not somehow blocking the device. The host should not mount that partition, but I can manually mount the device using the fstab entry.

I have attempted some old suggestions around disabling auto-mounting devices in settings > removable storage > removable devices however no devices show in that window. Another suggestion was to remove ~/.config/kded_device_automounterrc but that did not make a difference.

Trace from gdb Dolphin showing the error, sorry not sure how to use this tool or use to capture login details - and it's not a crash per se.
