This shows that interface-version is the (new) cultprit.
You can rename it to avoid a collision - or if you don't need it, you can
simply omit it:

    #lang racket
    (require net/url
         web-server/dispatchers/filesystem-map
         (rename-in web-server/dispatchers/dispatch-files
                    (make dispatch-files))
         (except-in (rename-in web-server/dispatchers/dispatch-sequencer
                               (make dispatch-sequencer))
                    interface-version))
