Unable to start server (packages installed from AUR)

I have installed both `sonic-pi-tool` and `sonic-pi-git` from AUR on Arch.

If I run a check, while the Sonic Pi GUI is open, I get:

```
❯ sonic-pi-tool check
Sonic Pi is not running properly, or there's an issue with the port numbers
```

I couldn't find anyone else with this issue so I'm opening one, thanks for the help!
