I was able to resolve this issue by sourcing and running the launch file by using /bin/bash -c

ExecStart=/bin/bash -c 'source /opt/ros/foxy/setup.bash; source home/$USER/dev_ws/install/setup.bash; ros2 launch pkg_name launch_file_name.launch.py; sleep 60'

Hi there, why do you have sleep 60? How is this important? Some sort of protection?

not that necessary, just gave it 60 sec before it starts again. If you have any other processes that need to close before you restart this might be a good option.
