What happened

When I register this tmLanguage.json file via Options -> Editor -> Language Servers: /~https://github.com/Leathong/openscad-support-vscode/blob/master/syntaxes/scad.tmLanguage.json and I open a file, doesn't matter whether it is empty or not, I got this exception:

Also syntax highligthing is not 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
