STEPS TO REPRODUCE
1. Connect or disconnect the wacom tablet. Notifications widget gets ignored and plasmashell crashes. It happens on Wayland. On x11, notifications did show up when wacom tablet connects and disconnects but randomly it'll crash.
2. On test account (freshly new), notifications also get ignored when wacom tablet connects or disconnects. Plasmashell crashes. On x11, notifications widget did show up when wacom tablet connects and disconnects. Haven't crashed in yet. 
3.  Crash is reproduceable when select both notifications widget and wacom widget set to "Shown when relevant" or "Always hidden".

ADDITIONAL INFORMATION

I used "Run Interactive Debugger" on Crashed Processes Viewer. Although the last few lines has ?? on it so I'm apologized if its incomplete again. ><
Comment 1 RyougaLolakieIV 2025-11-16 22:10:59 UTC 
notify-send "testing" on the terminal makes notification appear normally on wayland.

Comment 3 TraceyC 2025-11-21 20:48:34 UTC 
I'm not able to immediately reproduce the crash on Plasma built from git-master or on 6.5.2 using notify-send
I also don't see a crash when my bluetooth earbuds connect

These systems have Qt6.9.3, it's possible this is a Qt related crash

Yeah, also I tested on a fresh user account, and I didn't get any crashes but what I'd observe is that the crash is definitely related to the that known bug where you're trying to disable the app widget in the system tray config settings and pressing okay, it crashed. However, I did discover that bug myself, however, the crash didn't happen until I connected my wacom tablet. So I rebooted my pc, trying to replicate the crash by turning on my wacom tablet and turning it off, but no available.

I don't have a wacom tablet but my plasma shell was randomly crashing some time after playing around with widgets. for example one of the bugs I raised (marked as duplicate here) happened last week after I reconfigured something in the system tray - the crash did not happen immediately whilst I was doing something, but some time later. I then have not had a crash all weekend until today's crash (also marked as a duplicate here), and today I was once again editing some widgets but the crash happened maybe 30-60 mins after I had edited them

I do have a usb switcher which means I get notifications sent every time I switch it, but the events to reproduce this ( in my case at least ) seem to be something like:

configure system tray / edit some widgets 
trigger a notification
wait some period of time
observe plasma shell crash

Just to add that my system info is as follows:

Operating System: Fedora Linux 43
KDE Plasma Version: 6.5.3
KDE Frameworks Version: 6.20.0
Qt Version: 6.10.1
Kernel Version: 6.17.8-300.fc43.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 5800X3D 8-Core Processor
Memory: 32 GiB of RAM (31.2 GiB usable)
Graphics Processor: AMD Radeon RX 9070 XT

So definitely still happening beyond Qt6.9.3

For the minute I've cleared down ~/.cache to see if that has any effect

Today my plasmashell crashed right as a notification was received - looks like clearing the cache down made no difference. My other bugs have been marked as a duplicate of this one so I'm not sure if I should continue to submit crash reports. The crash seems random as it doesn't happen every time a notification is produced

Here's the relevant snippet:

The original bug report from RyougaLolakieIV is about a crash in Solid::DeviceNotifier::deviceAdded, which is Bug 470321.

kde49861515's bug report is something else; I'll un-dupe it and make it a new master bug report for the issue.
