Your environment

Which OS do you use: MacOS Sequoia 15.3 (M2 Pro)

Steps to reproduce

  1. Install GHC 9.8.4 using GHCup
  2. Compile HLS using the command ghcup compile hls --ghc 9.8.4 --git-ref master --git-describe-version
  3. Create a new stack project stack new sample-project new-template
  4. Open this new project in vscode with vscode-haskell extension enabled and running

Expected behaviour

vscode-haskell should load successfully.

Actual behaviour

vscode-haskell loads but hangs on "Processing: n/n" even on a new project. I suspect this might be because of an IntMap exception being thrown

Include debug information

Execute in the root of your project the command haskell-language-server-wrapper --debug . and paste the logs here (you can find the executable location here):
