-- Information about the crash:
- What I was doing when the application crashed:

System has bootet. Directly after showing the desktop, which took some time, the Plasma icon appeared and told me that Plasma crashed.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

"The reporter is unsure if this crash is reproducible." No, it happens after every system shutdown and reboot.
Comment 2 Nate Graham 2023-06-05 17:03:24 UTC 
I'm afraid Plasma 5.24 is unfortunately no longer eligible for support or maintenance from KDE.

Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. Please update to Plasma 5.27 as soon as your distro offers it to you. If you need support for Plasma 5.24, please contact your distro, who bears the responsibility of providing support for older non-LTS releases.

If this issue is still reproducible in Plasma 5.27 after you upgrade to it, feel free to re-open this bug report.

Thanks for understanding!

Re-opening since we got a report from Plasma 5.27.7.
