[Haskell-cafe] STATUS_DLL_NOT_FOUND from HLS 1.7 on Windows 10/11

Dear cafe,

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.
