Need help to debug why i get OOM and sddm fails on bootc project

Been spending almost 24 hours now figuring and trying to get my bootc project hit sddm and each time i get little closer atleast i have now more logs to see half of the time spend didnt have any logs and build failing etc. There seems to be constant theme that no user, no sddm and services/daemons get OOM kiled.

just cant understand what i have missed on this one

Turn it off or set it to act less agressive or assign more RAM to the VM.

or perhaps configure a disk based swap file.
