        programs.zsh = {
                initExtra = ''
                source ${pkgs.unstable.zsh-vi-mode}/share/zsh-vi-mode/zsh-vi-mode.plugin.zsh
                zvm_after_init_commands+=("[ -f $(fzf)/.fzf.zsh ] && source $(fzf)/.fzf.zsh")
                '';

Basic examination

• I have read through the README page
• I have the latest version of zsh-vi-mode
• I have tested with another terminal program

workaround

use zsh-vim-mode and source the fzf in accordance to nixos doku after the plugin

            initExtra = ''
                source ${zshExtensionsDir}/zsh-vim-mode.plugin.zsh
                if [ -n "${commands[fzf-share]}" ]; then
                  source "$(fzf-share)/key-bindings.zsh"
                  source "$(fzf-share)/completion.zsh"
                fi
                '';

I can confirm. Moreover, c-f functionality is also gone.

Btw: in normal mode, C-R is working for me.
