Posting this in case it saves someone some headache

I’m running Kubuntu 24.04 after upgrading Google Chrome from 153 to 154 plasmashell began crashing on every login.

It initially looked like a kernel or AMD GPU regression because the problem appeared after suspend and persisted after reboot, but after a bit of gooling it turn out it's very comman even on Fedora and is pinned post on /r/kubuntu sub

Only durable fix is to downgrad or just not upgrade
