Backtrace saved with "Crashed process viewer" app
SUMMARY
After upgrading my PC with KDE Neon 22.04 to the 24.04 Ubuntu base, the Plasma
desktop environment is completely unusable as it crashes instantly after login.
It doesn't restart so it could be used after this, and manually starting it
(with the command: kstart plasmashell) resulted in exact same behavior:
crashing instantly so that desktop background and icons only appear in a flash,
and then disappear. Backtrace of the crash, saved via "crashed process viewer"
app has been attached.
STEPS TO REPRODUCE
1. after receiving the notification on the (up-to-date) KDE Neon 22.04 computer
about the availability of 24.04 upgrade, click to start upgrade, and proceed
with the upgrade
2. after the upgrade is complete, log in to the system that now has the 24.04
base
3. Plasma will crash instantly and won't recover, starting it from a terminal
produces the same outcome.
OBSERVED RESULT
Plasma desktop is completely unusable on the KDE Neon after upgrading to the
24.04 Ubuntu base, since it crashes instantly when launched and doesn't ever
recover from the crash. It basically results in a distribution without a
desktop environment.
EXPECTED RESULT
Plasma desktop should work normally on Neon with the 24.04 base, meaning being
usable and recovering immediately
from any sporadic crashes
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE Neon 24.04 User edition
Plasma 6.2.0
KDE Frameworks 6.6.0
Qt 6.7.2
Graphics processor: AMD Radeon
ADDITIONAL INFORMATION
Some further information that might be useful: I have two panels, one default
panel (almost) and a small one to the left side of the screen, both set to
auto-hide. I also choose "Remove" for obsolete/broken packages during the
upgrade to 24.04.
