Tmux not starting from script

\#!/bin/bash

\#python study workspace

hyprctl dispatch workspace 1

hyprctl dispatch exec "kitty -e sh -lc '/usr/bin/tmux a -t cs50p || /usr/bin/tmux exec bash'"

sleep 2

hyprctl dispatch exec brave "https://www.youtube.com/playlist?list=PLhQjrBD2T3817j24-GogXmWqO5Q5vYy0V \\
