picom crashed when started.

I downloaded picom through pacman and also yay and both versions crashed.
Here are the log files

I don't know what causing it??

Neither can we.
Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General (the entire file, the link is to explain where to look for it, don't copypaste random blue boxes into an interactive shell)

Also

Aborted                    (core dumped) picom

https://wiki.archlinux.org/title/Core_d … _core_dump
but your entire glx setup seems borked, so let's look at the Xorg log first.

glx_init ERROR ] Failed to get GLX context

this make me think it's something to do with your picom config we would like to see your picom config.

Did you set the backend to backend = "glx"; if so, try xrender or xr_glx_hybrid also your de/wm will be helpful to know as example awesome (being a wm) can be handled by picom which won't conflict with it's own composting
as with a de e.g. plasma/gnome do compositing on their own. Which can be conflicting with picom, did you disable it, if using a de

side note you don't need to use yay that way, if the package is in the native repo use pacman -S, unless you install the git version, which will still crash if your config is set to glx
