Cannot start code server

[LJ-03]

I've tried configuring code-server so many times by this guide and troubleshooting online, but I just cannot get it to work.

I already had my Raspberry Pi set up with internet access via WiFi, not USB-C Ethernet like the Ben Hardill guide and this one. I've followed the setup from setting up code-server to the letter multiple times and I still fail to launch code-server when I check the code-server status. Here's the logs:

code-server.service - code-server
     Loaded: loaded (/lib/systemd/system/code-server.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Tue 2022-02-22 17:25:57 AEST; 32s ago
   Main PID: 6601 (code=exited, status=203/EXEC)
        CPU: 6ms

I'm very lost! I actually really liked your guide, so simple and the steps here are easy to follow but I just can't figure out this last step!
