SUMMARY
Around 3-4 weeks ago (I'm on Arch Linux, updating frequently), it started to crash, seems like early after boot (so I have to call plasmashell from terminal - a few times until it stops crashing).

Sorry if it's a duplicate; it's above my level to figure out.

STEPS TO REPRODUCE
1. Start the system, log in
2. Wait a while (I usually have Firefox opened at that moment)
3. Observe crash (no task panel)
4. Open a terminal, call plasmashell
5. It crashes again, start from #3 a few times

Comment 1 furioness 2025-09-15 14:49:43 UTC 
Also, I have a hidden taskbar. When I move my cursor down to it (before it crashes), I can see the audio icon displayed as either muted or uninitialized; then it crashes after a second.
Comment 2 TraceyC 2025-09-16 00:07:54 UTC 
I had the same crash happen. I had woken the laptop from sleep. After I plugged in the docking cable and plasmashell crashed after starting to initialize the external displays.

I have not seen this on another system running git-master

I found an older bug report with the same backtrace, so I'm merging this in with the other. Please follow bug 509192 for updates. Thanks!
