You want check whether this also affects a new user (environment or specific plasmashell configuration, the visitChildren looks a bit recursive) and whether you're exporting QSG_RHI_BACKEND=software anywhere
But at least we now also have a usable backtrace:

I was able to solve the bug in the end. As I was trying to start plasmashell from the terminal, I noticed that there were errors about some applet having an invalid with. This was weird, because the only Desktop applet I used was two taskbars with petty usual configurations.
Anyway, I just needed to reset my Desktop with rm ~/.config/plasma-org.kde.plasma.desktop-appletsrc, rm ~/.config/plasmashellrc and rebuild it.

Re: [SOLVED] plasmashell keeps crashing
Thanks for your quick response, I don't think I've exported QSG_RHI_BACKEND anywhere. I did try creating a new user and was able to log in without plasmashell crashing on me and also tried
rm ~/.config/plasma-org.kde.plasma.desktop-appletsrc ~/.config/plasmashellrccrashing still occurs in current user.

Re: [SOLVED] plasmashell keeps crashing
echo $QSG_RHI_BACKENDhttps://bugs.kde.org/show_bug.cgi?id=505670#c2
Run kcmshell6 qtquicksettings and put it back to automatic.

Edi: wayland or X11? Do you get different behavior w/ the other display server?

Greetings, I am experiencing the very same issue. After running pacman -Syu and rebooting, Wayland Plasma stopped working properly. Moreover, the option to use X11 Plasma no longer shows up in SDDM. Granted, I use Wayland because X11 purely does not work with my setup.
I also tried deleting the files mentioned above and it did not fix it. I get a segmentation fault, but am currently unable to share the dump because plasma keeps crashing after crashing. From what I gathered, it cannot open library files - most likely because the newly updated libraries broke old dependencies.
Is the only option to downgrade all packages to the previous version?

Re: [SOLVED] plasmashell keeps crashing
QSG_RHI_BACKEND was not set in my case. By running
kcmshell6 qtquicksettingsand setting rendering backend to automatic fixed it for me, thank you seth.

I can confirm that this works. When I ran the commend, I discovered that, for some reason, the renderer was set to software instead of automatic. Setting it to automatic fixed my issues, too.

Yep, seems like this was a broken config. Thank you for helping us solve this issue!
