HLS 2.8 sometimes gets stuck on startup about haskell-language-server

[rmullin7286]

I can verify that I'm getting the same issue, and I'm able to reproduce it consistently. Basically, I have to wait for about 5-10 seconds after neovim opens a haskell file to start typing or else I hit the same case as @MangoIV.

Basic repro steps:

1. Create a new cabal project with a Main.hs
2. As soon as a haskell file is opened in neovim, begin modifying the file so that the code is incorrect (for example, delete the argument to putStrLn).
3. The LSP hangs indefinitely

The odd thing is, this behavior continues even after I attempt to reboot the LSP. I have to completely close out of neovim and restart to get it working again.

I've attached the log file from when I was reproing this. I used the --debug flag as suggested.

As well, I seemed to get these errors when saving the file in neovim:

The incorrect indentation or mismatched brackets error persists even when the code is this in my editor:

module Main where

main :: IO ()
main = putStrLn "foo"

Which seems to tell me that haskell-language-server got stuck looking at an old version of the file.

Could you add some logs where this particular issue happens? Perferably with --debug?
