Seems like sddm-greeter-qt is crashing with graphics driver issues.

SDDM is technically not a KDE project, and it's also somewhat odd that this process would keep running in the background, and that it crashing would take down the session. It seems that your system is not configured in an optimal way. I would recommend following up with your distro's packagers and power users about this.
