Not much we can say about this with no debug symbols. Can you install some, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Fedora Thanks!

Created attachment 137701 [details] New crash information added by DrKonqi plasmashell (5.20.5) using Qt 5.15.2 What I was doing when the application crashed: I have just launched Plasma on Wayland. I have set up my two external screens. They are connected via an USB-C Dock (Lenovo) to a Lenovo ThinkPad T490. When dragging the main panel (window switcher, clock, indicators) to a different screen, it looked like plasmashell has crashed. The screen went black. Then one window re-appeared centered on the middle screen. The windows were still there, I can launch applications with krunner. There is just no panel. I'll try to restart plasmashell once I have submitted this report such that I don't lose the trace. -- Backtrace (Reduced): #6 0x00007f832097148f in qt_message_fatal (message=<synthetic pointer>..., context=...) at global/qlogging.cpp:1914 #7 QMessageLogger::fatal(char const*, ...) const (this=this@entry=0x7fffce10bf70, msg=msg@entry=0x7f831e979ed0 "The Wayland connection experienced a fatal error: %s") at global/qlogging.cpp:893 #8 0x00007f831e8fded4 in QtWaylandClient::QWaylandDisplay::checkError() const (this=<optimized out>) at qwaylanddisplay.cpp:211 #9 0x00007f831e8fe0ea in QtWaylandClient::QWaylandDisplay::flushRequests() (this=0x564600d51360) at qwaylanddisplay.cpp:222 #10 0x00007f8320b713c0 in doActivate<false>(QObject*, int, void**) (sender=0x564600d6fc00, signal_index=4, argv=0x7fffce10c080, argv@entry=0x0) at kernel/qobject.cpp:3898
I have just restarted plasmashell, it came right back up. And then I have dragged the panel to the middle screen; this time without any issues. Hopefully the backtrace will be of some use. I'll come back if it should appear again.
No, it is still not actionable. :( There's just no information there.
