Omnisharp language server not working

[terpyderp]

I'm trying to use the OmniSharp language server for code completion in Helix.
I followed the instructions here https://github.com/helix-editor/helix/wiki/Language-Server-Configurations#c but it doesn't seem to be working in editor.

Here's the output of hx --health c-sharp:

Configured language servers:
  ✓ OmniSharp: F:\Stuff\Programs\_Path\omnisharp-win-x64\OmniSharp.exe
Configured debug adapter: netcoredbg
Binary for debug adapter: 'netcoredbg' not found in $PATH
Configured formatter: None
Highlight queries: ✓
Textobject queries: ✓
Indent queries: ✘

Here's the relevant part of helix.log when I open a .cs file in my Unity project

Update: I got it to work! Apparently I was on an old version of Helix that I installed through winget. Installing the newest version from the GitHub releases and running :lsp-restart after opening a .cs file fixed the problem!
