This should have been fixed a while ago; can you upgrade to Fedora 34 and see of it still happens?
Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone!
When logging out & in again, I see all kinds of weird behaviour, sometimes crashes on login, sometimes wifi does not work anymore - and sometimes everything works as expected. I'll give the usb live system a try, F34 changed quite a bit and to be honest I am a bit reluctant to see my production desktop broken again (wayland) or without audio (pipewire) ;)
what I find interesting - most of the time, those bugs are catched by the system-wide bug reporting utility (ABRT), only on rare occuasions the kde bug reporter is able to catch a crash. This seems to be a sad thing, because the bugs filed at redHat usually are not noticed by anybody and every 6 months I get about 20 emails regarding bugs that will be auto-closed because their reported release is approacing EOL.
