working. ### How to reproduce * Open Tools -> Options -> Editor -> Language Servers and register a new filetype for "scad SCAD" extension * Download this file: https://github.com/Leathong/openscad-support-vscode/blob/master/syntaxes/scad.tmLanguage.json and add this as the syntax grammar * Add an icon or not, doesn't matter * Save, apply and hit ok * Open an empty *.scad file or any other example (You can find one here: https://files.openscad.org/examples/ * File took very long to open and inside the notifications you can see the error ### Did this work correctly in an earlier version?
