[Solved] XWayland segfault

[BurningMemory]

Hello there.
GPU: NVIDIA RTX 3060 Ti
Driver version: 535.54.03
Kernel: 6.1.31
Portage: 3.0.46 (python 3.11.4-final-0, default/linux/amd64/17.1/hardened/selinux, gcc-12, glibc-2.36-r8)

dev-libs/wayland-1.22.0::gentoo USE="-doc -test" ABI_X86="(64) -32 (-x32)"

x11-base/xwayland-23.1.1::gentoo USE="(selinux) xcsecurity -unwind" VIDEO_CARDS="nvidia"

There are no errors in dmesg or sddm.log, no others that i can check as when i start the session i become unable to use my keyboard and mouse.
All i see is a black screen with a mouse cursor. And yes, i have SELinux enabled, although it is in permissive mode and my filesystem is properly labeled.
Interesting logs:

Then i just have to reboot manually. Do you guys have any advice?

Edit: The issue appeared upon restart after i've done some configuration with the system.
Resetting the configs doesn't help, i've also tried to compile Plasma's stuff with the "screencast" USE flag.
Recompiling without the flag doesn't seem to help.

Can't help but notice the Nvidia drivers you are using are unstable.
The latest stable is 525.116.04-r2
Why don't you try the stable driver and let us know how you get on?
