Help fix third party package

Yesterday at 11:25:03

Hello everyone!

I want to use greeter for LightDM from the Elementary OS project, which is developing its own Pantheon desktop environment, which I am currently testing on Artix. I built and installed the `lightdm-pantheon-greeter` package and restarted LightDM. I did not make any changes to `/etc/lightdm/lightdm.conf`, but I was greeted by a beautiful login screen.

But as soon as I log in, problems begin, namely: two wingpanels open instead of one and they overlap each other; the clock, date and map with the user selection do not disappear; greeter starts loading the CPU core by 100%, which is why the fan hums.

It is important to note that I would like to fix this, not replace DM or greeter itself!

I will provide all the logs below, but if this is not enough, I will post the requested information upon request. I hope for your help!
