SUMMARY Upon boot an error message cover the wallpaper with a crash report: Application: kdeinit5 (kdeinit5), signal: Aborted One or more startup apps do not launch eg pulseaudio-dlna in Konsole Right clicking the desktop and refresh removes the wallpaper error message. An issue which developed simultaneously is the absence of favourites and recent applications in both Simple & Application Launcher. STEPS TO REPRODUCE 1. Boot into Kubuntu OR 2. Right click desktop and change location option for desktop folders OBSERVED RESULT Application: kdeinit5 (kdeinit5), signal: Aborted [KCrash Handler] #4 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:49 #5 0x00007fa447d20864 in __GI_abort () at abort.c:79 #6 0x00007fa447f72ba3 in QMessageLogger::fatal(char const*, ...) const () from /lib/x86_64-linux-gnu/libQt5Core.so.5 #7 0x00007fa448d04208 in ??

Hello Nate, Thanks for the link! So in searching for a debug tool I searched both the web, bug.kde.org and Muon package manager for all things and keywords related to: kdeinit5, kio, activities etc but cannot find anything relevant. I found mention of both kio-extras-dbgsym and kdelibs5-dbgsym which sounded like they may be helpful - but they are not in Muon nor would a apt install work. They do not appear to be in the Kubuntu 20.10 repo. The crash report also states - You cannot report this error, because kdeinit5 does not provide a bug reporting address. Is there a debug tool available? Thanks,
Ok, I got kio-extras-dbgsym installed. The KDE crash reporter gives the same information though. Is there a command to execute kio-extras-dbgsym? If it is at all relevant!
Actually it is a little different - but is it anymore informative??

Muuuuuch better, thanks. #8 0x00007f7d6b3059fd in ActivitiesProtocol::listDir (this=0x7ffd39481cc0, url=...) at ./activities/KioActivities.cpp:251 #
RESOLVED: Navigating to ~/.local/share/kactivitymanagerd/resources and deleting database + database-shm + database-wal makes the crashes go away This has resolved both the start up error/crash as well as the launcher being blank.
That means there was corruption in the database, which means it was probably the same thing as Bug 427650, which was fixed in Plasma 5.20, so this makes sense since you're still on Plasma 5.19. *** This bug has been marked as a duplicate of bug 427650 ***
