Sentry Crash Report:

Description zacharytalis 2024-06-22 03:17:23 UTC 
Application: plasmashell (6.1.0)

Qt Version: 6.7.1
Frameworks Version: 6.3.0
Operating System: Linux 6.9.5-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.1.0 [CoredumpBackend]

-- Information about the crash:
Updated my desktop from KDE 6.0 to KDE 6.1, and can no longer launch plasmashell in a Wayland session. X11 remains unaffected.

SDDM works normally. Upon login, three DrKonqi plasmashell crash report windows appear. There aren't any wallpapers or widgets, but my cursor is still functional and I can launch programs using shortcuts.

Launching plasmashell using "/usr/bin/plasmashell --no-replace" results in the same immediate plasmashell crash.

I can provide more info as needed <3

Ask your distro to rebuild everything with plasma-wayland-protocols 1.13. We forgot to bump the version requirement, oops.
Comment 2 zacharytalis 2024-06-28 03:06:38 UTC 
I filed a bug with the plasma-workspace package on Arch, and received a response from maintainer Antonio Rojas:

"No, upstream is wrong. It isn't even possible to build Plasma with older plasma-wayland-protocols"
https://gitlab.archlinux.org/archlinux/packaging/packages/plasma-workspace/-/issues/5#note_193861

I've reopened this issue accordingly.
Comment 3 zacharytalis 2024-07-06 21:53:08 UTC 
I learned how to read a backtrace, and completely resolved my issue!

--> tl;dr it's my fault, my kwayland was out of date... <--

The long version: over a year ago, I experimented with KWinFT, which required installing the git version of kwayland from the AUR, kwayland-git.

*-git packages are special, because the onus falls on users to rerun installation after a version bump. (The AUR makes wayyyyy more sense to me now. Bumps don't come from nowhere!)

Fast-foward to the present, and I'm trying to find "wayland-plasma-window-management-client-protocol.h" from the backtrace. I attempt to build plasma-workspace for myself, and receive the error:

`Could not find a configuration file for package "KWayland" that is compatible with requested version`

Looking through the partially-completed build, I don't spot my desired file. So I double-check my installed kwayland version, and... yep!

I've changed the title of this bug report. Original title: "Plasmashell immediately crashes on Wayland+NVIDIA"

Here's the guide that taught me how to read a KCrash backtrace: http://floss.booktype.pro/kde/reading-backtraces/
