Steps to reproduce

I honestly don't know what causes this, but it happens every time I open my private project.

Expected behaviour

I've seen that error before in the cabal issue tracker: haskell/cabal#7456
Does the build succeded out of hls? is the error throwed if you run haskell-language-server -d . in the project root dir (attach logs if it is so, please)?

[ilyakooo0]

Yes, the issue is still reproducible when I call haskell-language-server -d ..

@jneira I sent you an email with the logs.

[jneira]

Thanks, i've took a look and i dont see nothing wrong until the crash. The error is shown just after loading path/to/Server.hs.
I guess haskell-language-server -d path/to/Server.hs alone will throw it again. If it is so maybe you could indentify some property of that module which might be related with the error

[pepeiborra]

Have you tried building an HLS binary from source with -dynamic?

[bgamari]

Which GHC version was this observed with?

[ilyakooo0]

GHC 8.6.5

[ilyakooo0]

I compiled HLS from source with the same version
