nevermind:
I use this commands and fix it after the reboot,
it delete all of my themes, but it solve the bug.
I like a nuke for kde at least for the customization part.
rm -rf ~/.config/plasma-org.kde.plasma.desktop-appletsrc
rm -rf ~/.config/plasmashellrc
rm -rf ~/.config/kdeglobals
rm -rf ~/.config/kded*
rm -rf ~/.config/kactivitymanagerd
rm -rf ~/.config/kcm_*
rm -rf ~/.config/kglobalaccel*
rm -rf ~/.config/kirigami*
rm -rf ~/.config/kwinrc
rm -rf ~/.config/kscreenlockerrc
rm -rf ~/.config/kwin*
rm -rf ~/.config/kio_uiserver
rm -rf ~/.config/ksmserverrc
rm -rf ~/.config/kded*
rm -rf ~/.local/share/plasma*
then:
rm -rf ~/.kde4
then:
rm -rf ~/.cache/*
rm -rf ~/.local/share/kscreen*
rm -rf ~/.local/share/konsole*
then:
reboot
and it fix my taskbar.
Thanks for the support.
