SUMMARY
I have been attempting to install fcitx5 and the combo keys to switch language did not detect, so I gave up with the leftover of fcitix5 that did not remove completely. Also same as ibus-libpinyin with no luck. Run steps with the help of chatgpt most of the time for precise comprehension. 

Issue that I observed are both clean uninstallation and installation. Btw I am new to Linux.

Please don't use AI to debug your issues or report bugs.

Assuming the PDF you attached is accurate, it shows that your QT_IM_MODULE environment variable is still set to fcitx, which means IBus isn't actually active.

Next time, please post requests for help with configuration issues on discuss.kde.org rather than reporting them as bugs. Thanks!
