[SOLVED]High resource consumption when starting konsole in KDE X11

I am using KDE Plasma 6.0.4 in X11 session.
When I launch Konsole in an X11 session, the Konsole process occupies 100% CPU and 13GB of memory (my computer only has 16GB memory), and kswapd also consumes 100% CPU. They use such a lot resource until Konsole opens.
Additionally, Konsole opens very slowly, taking about 17 seconds.
However, in a Wayland session, there is no such issue, and the time to open Konsole does not exceed 1 second.

This is the result of pacman -Qikk xdg-desktop-portal-kde:

You are likely starting something huge in your bashrc or similar. Check/post the contents of that.

Thank you for your advice, but I don't believe my issue is caused by the case you described.
I usually use zsh. I put all my stuff in zsh configuration files, and my bash configuration files are all default.
However, after I changed the shell inside Konsole from zsh to bash , ran

chsh -s /usr/bin/bash

and rebooted my computer, the problem still persists.

I used to use Win11 icon theme. Problem solved after changing icon theme to breeze. Strange problem.
