Well spotted, thanks!

You will need to fix all the stack descriptors and modify the following line:

haskell-language-server/haskell-language-server.cabal

Line 306 in 1b69975

if flag(brittany) && (impl(ghc < 9.0.1) || flag(ignore-plugins-ghc-bounds))

[Anton-Latukha]

Well, brittany release for 9.0.1 has aeson >= 2.0.1, & lsp-types currently has aeson < 1.6 bound (lsp-types already had release with aeson 2.0 support but due to something made a revision). Opened haskell/lsp#373 to remind on this.

Considering it is more efficient to close this, to free space for future more complete update continuations from community.

I am continuing this in https://github.com/jneira/haskell-language-server/tree/brittany-9.0.1
It will need a massive amount of changes to make hls support aeson >= 2.0.1 (see ennocramer/floskell#68 for example)
