Created attachment 136105 [details] Filtered stacktrace of ksplashqml SUMMARY Upon login, after the splash screen is displayed, I am taken to a black screen, so I assume plasma shell is not loaded. Is this related to bug #432364 : ? https://bugs.kde.org/show_bug.cgi?id=432364 Operating System: Arch Linux KDE Plasma Version: 5.21.1 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 Kernel Version: 5.11.1-arch1-1 OS Type: 64-bit Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 PRO 4750U with Radeon Graphics Memory: 14.9 GiB of RAM Graphics Processor: AMD RENOIR ADDITIONAL INFORMATION I am attaching a filtered stacktrace of the crash as obtained from `coredumpctl info`.
Also, as before (i.e., v5.21.0), when I add the environment variable "KDE_DEBUG=1" to the [Serivce] section of the plasma-plasmashell unit file, it does not give me a blank screen, and actually starts plasmashell.
