Additional context

Same error occurs every time when opening a .rkt file, and any feature related to LSP does not work. Other features, such as syntax highlighting and REPL, work well. I have raco and racket in my PATH, and racket -l racket-langserver only shows:

(racket:8704): Gtk-WARNING **: 11:45:28.748: Theme parsing error: gtk.css:73:46: The style property GtkScrolledWindow:scrollbars-within-bevel is deprecated and shouldn't be used anymore. It will be removed in a future version

This is weird. Have you tried looking at this issue: jeapostrophe/racket-langserver#45 and trying their workaround? Seems to be related, maybe you have an old version of gtk or something.
