set -g @tmux-fzf-launch-key "a"

Because you bind the key to a. You should press prefix + a to launch it.

it was working changing the source code in ~/.tmux/plugins/tmux-fzf/main.tmux

before

#!/usr/bin/env bash

CURRENT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

source "$CURRENT_DIR/settings.sh"

set_launch_bindings() {
	local key_bindings=$(get_tmux_option "$launch_key" "$default_launch_key")
	local key
	for key in $key_bindings; do
		tmux bind-key "$key" run-shell -b "$CURRENT_DIR/main.sh"
	done
}

set_launch_bindings

after

#!/usr/bin/env bash

CURRENT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

source "$CURRENT_DIR/settings.sh"

set_launch_bindings() {
	local key_bindings=$(get_tmux_option "$launch_key" "$default_launch_key")
	local key
	for key in $key_bindings; do
		tmux bind-key "$key" run-shell -b "$CURRENT_DIR/main.sh"
	done
}

# set_launch_bindings
tmux bind-key -T prefix F run-shell -b "$HOME/.tmux/plugins/tmux-fzf/main.sh"
