Adding KDE stock apps to image causes SDDM to break; possible versioning/package issue?

Apologies if this is the wrong place to ask for advice regarding this.

So I’m building a Fedora Atomic image for my own personal use, based on kinoite-main and the ublue template.

In the image I have some KDE utilities installed on the base layer instead of as Flatpaks. Initially, this seems to have worked well, but after a reboot following an upstream update yesterday, I noticed that SDDM is now completely broken, with a black screen and the inability to switch to other TTYs - the only option I have is rebooting.

After closer inspection, I found that the KDE packages on base required updating a lot of other Plasma components, including replacing plasma-workspace-wayland with plasma-workspace. This appears to be the root change that’s causing SDDM to hang - without this change SDDM works fine.

Given this only started occurring yesterday (the KDE packages worked posed no issue before then), I think further updates may correct this. However, I’m not sure if this versioning issue is from Fedora or the Universal Blue layers.

Any advice or tips on where to go from here? I strongly prefer to keep the KDE packages in the base layer instead of Flatpaks if possible.

On ublue’s discord, I’ve read that there’s been some issue in upstream Fedora, my KDE images are broken too. Apparently the fix has been pushed already, so just wait until it comes. Meanwhile you could pin the base image. I’m running a working build from 2025-06-27

The latest kinoite-main image works.
