```

There are errors from org.kde.plasma.notifications and org.kde.plasma.keyboardlayout packages, I assume the reason is in notifications.  Unfortunately, I don't know if it is possible to debug further without development environment.

Maybe it also depends on my system/user config, but keyboard layout and notifications are base parts of desktop environment, that's why I haven't tested with new generated config.

STEPS TO REPRODUCE
1. 
2.

ADDITIONAL INFORMATION
Comment 1 Andrey 2021-01-24 12:04:36 UTC
Hi,
I also have these org.kde.plasma.keyboardlayout errors but tend to expect they are normal.
Backtrace could be helpful.
But first, could you rename /usr/share/plasma/plasmoids/org.kde.plasma.keyboardlayout/contents/ui/main.qml and try again?
Comment 2 Vladyslav 2021-01-24 13:05:44 UTC
Yes, even without keyboardlayout plasmashell still doesn't start:

Comment 3 Andrey 2021-01-24 13:56:05 UTC
Yeah, it seems JS checks array boundaries anyway so this line can't be a problem:
https://lxr.kde.org/source/kde/workspace/plasma-workspace/components/workspace/KeyboardLayoutButton.qml#0014
I'll fix it to eliminate the error output, though.

I'm changing the Component from "Keyboard layout".
So to fix your problem, backtrace still might be needed.

Ok, thanks. Could you please also briefly explain or maybe there is a link with explanation how can I get a backtrace?
Comment 5 Andrey 2021-01-24 14:14:00 UTC
If you have coredumpctl i think this is the simplest,
the commands to go is something like this:

$ coredumpctl gdb
then inside opened gdb:
bt

You might need to install dev packages with debugging symbols, the command above will advice you if so.

Also I've tried to disable notifications plasmoid by renaming /usr/share/plasma/plasmoids/org.kde.notifications/contents/ui/main.qml and it didn't help.

These logs are from X Session because Wayland session doesn't start at all anymore.

I've installed more debug packages and in crash helper, there is the following backtrace, it's more informative as I see:

Thanks Vladyslav,
I'm not sure I'm experienced enough to help you here,
but are you sure it's not something with your setup?
Have you tried on new user/clean install in VM maybe?

Andrey, you are right.
First I've tried to create a new user and both X and Wayland sessions did work! Then I removed .cache directory in home of the old user and it starts. I don't know whether all things work but it starts at least.

Thank you!
Will other users not experience the same problem after the update to Plasma 5.21? If so can I somehow help to avoid that?
Comment 12 Andrey 2021-01-25 21:16:25 UTC
Ah, seems we got update problem..
It happens from time to time, and in my experience it rather unpredictable and hard to debug, so it's good we catch it here!
I'll rise attention to this problem, and from your side you could try to reproduce it if you want to help.
Otherwise, I can't really say if it ever hit other users. But might.

Thank you!
Comment 13 Andrey 2021-01-26 16:56:35 UTC
One more thing:
could you attach these backtraces as files?
It would be easier to analyze.
Comment 14 Nate Graham 2021-01-26 17:21:10 UTC
Backtraces need to be inserted as comments so that their text they appears in search results. Attachments aren't indexed.
Comment 15 Andrey 2021-01-26 17:44:14 UTC
May be, it's just hard to read it here so I think attaching them additionally doesn't hurt.
