Please help with a calva error

Calva repls (getting started repl or a project repl) with an error “ERROR: Unhandled REPL handler exception processing message {:op eval, :code ns, :id 1}”

Assuming this is the same issue: starting a repl fails out of the box. · Issue #2314 · BetterThanTomorrow/calva · GitHub

It was something about the WSL extension causing the repl to be started in docker. Unclear to me why that happens and why that fails in the way it does. But good if the solution in this case was to disable the WSL extension.
