Plasma crashes often and screen goes black at random

Help

Hello! My computer is crashing often for the past few days :(. The crashes seem to happen at random, sometimes it begins after I log in after the splash screen fades and sometimes it happens after a few hours of running, when I close a window.

It starts with a popup saying that Plasma has crashed. The toolbar disappears immediately after. I can’t click on anything either. Then the screen goes black and nothing works afterwards, only my cursor is visible.

I’m running Kubuntu which currently does not ship with Wayland. I installed Wayland via the CLI and started using that for a while, which went well for a few weeks up until this point. I’ve been using X11 for a bit and that has been going fine.
Thanks for any help!

Plasma version: 5.24.7
Kubuntu version: 22.04.4 LTS

lasma 5.24 - which is the latest you can get for Kubuntu 22.04 - does not really have good Wayland support and I recommend you go back to X11 until you upgrade.

Kubuntu 24.04 will come out very soon™ and it will bring Plasma 5.28 where Wayland support is very much improved (not as good as Plasma 6 has it - but very much daily driver quality).
