Hello, I have a black screen on startup after updating kde 24.04.1 LTS. I have this error that I got when starting with security graphics mode:
kernel: sof-audio-pci-intel-mtl 0000:00:1f.3: ASoC: error at snd_soc_dai_hw_params on iDisp3 Pin: -22
Me similar, also got a black screen on startup, but idk if my case is the same as yours.
I can push 3-finger up on touchpad and get into the desktop switching view, then launch apps with the search bar. It’s just the desktop (and the bars) missing, but non-black glitches could be seen occasionally.
This is similar to a crash experience of mine in April, where it was just after my migration to Plasma 6 & it was the fcitx5 build incompatible with qt6 that crashes the plasmashell.
At that time I found clues in journals and reported the bug, soon fixed thanks to the joint efforts of devs.
But this time the journal implies nothing about fcitx5 and the message is as the following:

Identical message could be found after restarting plasmashell with kquitapp6 plasmashell && killall plasmashell && kstart plasmashell.
It seems to say sth about Qt6 web engine is missing. In the upgrade prompt I chose to cleanup some obslate packages idk if it affects the problem.
btw I tried to boot in “security graphics mode” as you said, but idk how to do that. Google doesn’t teach it QwQ
Same issue I have been posting about since Plasma 6.2 was released.
A temporary workaround is to revert to terminal mode and then revert back to the plasma desktop
It happens when running EndeavourOS and CachyOS -- I finally realized the common denominator in addition to Plasma 6.2 is the monitor I am using. Apparently powerdevil, ddcutil and plasma-desktop contain the bug.
I have contacted one KDE website and also posted a bug notice there.
There was a Plasma 6.2.01 update that left the bug present.
A temporary workaround was to revert to terminal mode and then revert back to the plasma desktop
