Frameworks Version: 5.102.0
Operating System: Linux 6.1.12-xanmod1-dist x86_64
Windowing System: X11
Distribution: "Gentoo Linux"

-- Information about the crash:
I have no idea what I'm doing,

openrc 0.46, elogind 246.10-r2, xorg 7.4-r3, plasma-meta: Latest version available: 5.27.0 [Latest version installed: 5.26.5]

started xorg via startx

```
exec dbus-launch --exit-with-session startplasma-x11
```

updated to x11-base/xorg-server, and tried to launch settings before updating environment variables (env-update && source /etc/profile) or following gentoo migration guide xorg-x11 ==> xorg-server

The crash can be reproduced every time.

Comment 2 Nate Graham 2023-02-28 20:59:28 UTC 
All evidence points to a broken system. Please ask Gentoo folks for help with it.

JFYI if "I have no idea what I'm doing" is accurate, Gentoo might not be the ideal distro for you. :)
