Additional context
Add any other context about the problem here.

I tried code --enable-wayland-ime but does not help

here I tried both Fcitx5 Wayland and Fcitx5 but does not help

Since you are on Wayland, you can try unset QT_IM_MODULE and GTK_IM_MODULE to force the applications to use Wayland text-input protocol, see also:

Also, do you have --ozone-platform-hint=auto in VSCode startup flags? If you are using the visual-studio-code-bin package on AUR, it's better to set those flags in ~/.config/code-flags.conf:

--ozone-platform-hint=auto
--enable-wayland-ime

to force VSCode use Wayland window and input method protocol

So this has nothing to do with virtual keyboard if I have not installed any virtual keyboard app like cellwriter?
