Description Syboxez 2025-02-20 16:12:54 UTC 
SUMMARY
After upgrading to Plasma 6.3.1 from 6.2.5, kscreen-doctor shows the message "kscreen.doctor: Invalid config." and proceeds to hang until I "Ctrl+C" when trying to do anything, including "-j", "-o", and any output command. I have attempted to delete my kscreen config and even rename my entire ".config" with no difference

STEPS TO REPRODUCE
1. Run "kscreen-doctor -o" in a Wayland session
2. Observe the message "kscreen.doctor: Invalid config." and the hang

OBSERVED RESULT
Hanging program in Wayland, but works fine in X11.

EXPECTED RESULT
So function normally without error messages or hangs

Comment 1 Syboxez 2025-02-20 16:13:48 UTC 
The GUI display configurator works fine.
Comment 2 Syboxez 2025-02-20 16:27:23 UTC 
This issue was caused by user error. I was attempting to run an old version of kscreen-doctor that I locally built without knowing it.
