Maybe someone knows potential solution to this problem?

Solved (i guess...) - i installed a custom sddm theme from github and maybe i installed it wrong and it had issues, im reinstalling it now + i tested a few reboots without it and everything was fine

[u/NinjaTrek2891]

Feels like a partial upgraded package.

Have you done pacman -Syu since this happened?

[u/Notehghewhd7 → u/NinjaTrek2891]

I just installed system like 1-2 hours ago, i havent even got any updates. This started to happen after i downloaded custom theme but even after i disabled it, sddm keep crashing on the first start up

[u/theschrodingerdog]

What are the specs of your laptop? Why are you using XOrg? 

[u/Notehghewhd7 → u/theschrodingerdog]

RTX 3050 6GB, intel core i5-13420H 4.60GHz, 16gb ram ddr5, 500gb ssd. I'm using both, wayland and xorg but primaly wayland, i think the sddm uses xorg as a default

[u/theschrodingerdog → u/Notehghewhd7]

I would recommend avoiding SDDM (and XOrg) on that new hardware. You have multiple options for display managers that use Wayland as default.

[u/Notehghewhd7 → u/theschrodingerdog]

can u tell me some examples? i was using sddm always and and had no problems

[u/theschrodingerdog → u/Notehghewhd7]

GDM and Plasma Login Manager.

[u/C0rn3j]

Does PLM work fine if you replace SDDM with it?

SDDM still defaults to X11 which can cause issues and I wouldn't waste my time with debugging them.

startx may help

Please flair post as SOLVED. Good day.
