Public bug reported: Updating the HWE Kernel from 6.5.0-45 to 6.8.0-40 on Jammy/22.04-4 LTS (Kubuntu) causes systems using KDE to boot into black screen because plasmashell won't load. I couldn't find any suspicious messages inspecting the output of `dmesg -T`. Running `kquitapp5 plasmashell && kstart5 plasmashell` yields the message "Application plasmashell could not be found using service org.kde.plasmashell and path /MainApplication."
