Story

I installed this sddm theme from kde plasma, but it's only show red error message, so I tested it using sddm-greeter --theme win10-sddm-theme --test-mode.
I searched google and asked chatgpt, and ended with installing more debian packages including qml6-module-qt5compat-graphicaleffects. The result is error, so I decided to contribute to the source.
