How to reproduce the issue

I just downloaded the haskell-tools.nvim and entered a .hs haskell project built using cabal. HLS exits with code 127 and signal 0 when I enter a .hs file. Idk how to fix this, I fixed the conflicting configs

Expected behaviour

HLS does not crash with exit code 127 and signal 0, just works

Actual behaviour

HLS exits with code 127 and signal 0, HlsStart reproduces this behaviour, I have tried installing HLS locally and via Mason, both produce the same output

Log files

No response

The minimal config used to reproduce this issue.

Idk what could cause this conflict, lsp does not setup Hls at all:
heres the lspconfig fn
mason_lspconfig.setup_handlers {
  function(server_name)
    if server_name == "hls" then
      return
    end

    require('lspconfig')[server_name].setup {
      capabilities = capabilities,
      on_attach = on_attach,
      settings = servers[server_name],
      filetypes = (servers[server_name] or {}).filetypes,
    }
  end,
}

Sorry I can`t describe more in depth what the error is, I am still new to neovim and haskell.

btw heres logs from the lsp, I figured out how to get them. logs.
