Failed to activate systemd service

I have a personal Conky script (at ~/.conky/conky-launch.sh) that I'd like to execute every time I boot up my OS (which is Fedora Workstation 39). So, I created a systemd service file named personal-conky.service as follows:

[Unit]
Description=Opens up my personal conky setup on boot

[Service]
User=arch
ExecStart=/home/arch/.conky/conky-launch.sh

[Install]
WantedBy=multi-user.target

Next, I enabled the service by doing:

$ sudo systemctl enable personal-conky.service

When I rebooted however I found that the script has not executed. When I did:

$ systemctl status personal-conky.service

I got the following error:

× personal-conky.service - Opens up my personal conky setup on boot

Why is this happening, and what should I do to fix this?
