Please report this as a GHC bug:  https://www.haskell.org/ghc/reportabug

I think it's related to a reported ghc bug: https://gitlab.haskell.org/ghc/ghc/-/issues/16996 -- HLS crashes only when loading projects where we are not able to use module completions in ghci, as discussed in the gitlab issue.

@berberman this can be closed by #1367 or we could do something to improve state of things?
I guess it is blocked on the mentioned ghc bug
