This is not minimal in any way, but this project is easy to get going and reproduces the issue: GitHub - ilyakooo0/grenade: Deep Learning in Haskell

To having the plugin start the Language Server:

  1. Install Stack: The Haskell Tool Stack
  2. stack build in the project directory to download and build dependencies
  3. Open the project with the plugin installedcomma
  4. Run the “Restart Haskell Language Server” command to download and start the language server.
