Created attachment 141584 [details] apologies for the blur, but what do I do here SUMMARY See photo of screen STEPS TO REPRODUCE No idea, I don't even mess around with theme files much. the max I've done is installed themes through the Get New (Stuff) dialogs, and I've never installed a SDDM theme either. OBSERVED RESULT Screenshot; sddm first has a virtual keyboard with nothing behind, then on dismissing the keyboard the SDDM with its fallback theme shows up and doesn't let me log in Error message: The current theme cannot be loaded due to the errors below, please select another theme. file:///usr/share/sddm/themes/breeze/Main.qml:26:1: plugin cannot be loaded for module "org.kde.plasma.core": Cannot load library /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma(something)core/libcorebindingsplugin.so: (/lib/x86_64-linux-gnu/libKF5Plasma.so.5: undefined symbol: ZN15KPluginMetaData11findPluginsERK7QStringSt8functionIFbRKS_EE) (this is what I could read the text; there could be typos. Just for reference before you look at the image) EXPECTED RESULT should work SOFTWARE/OS VERSIONS No idea about Qt or Frameworks, because I can't exactly check right now. OS: KDE neon 5.22 Plasma version 5.22.5 Basically stock KDE neon User edition, and I last updated 4 days ago. ADDITIONAL INFORMATION I do not recall doing anything with sddm themes, I was using the default, whatever that was.

Thank you for your bug report! However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since before 01/01/2025. Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's. Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report. Thanks for understanding!
