The bug report as-is is probably insufficient to be actionable, but maybe we are lucky and someone immediately has an idea.

A few of my students have encountered a problem running HLS 1.7 on Windows 10/11. Their Haskell installations mostly seem okay---everything installed by ghcup (1.8) , and cabal (3.6.2) and ghc (9.2.2) work as expected. However, when VS Code (via the Haskell plugin) attempts to start the language server, it exits repeatedly with error STATUS_DLL_NOT_FOUND (or its signed integer equivalent).

Has anyone encountered a configuration that leads to this problem before? Most of the students are not having this problem (nor am I, on similar software configurations), so I suspect it's a consequence of something else they have installed.
