Unable to change font in vs code

I was trying to change my vs code’s font to Roboto Mono, I installed it from google fonts https://fonts.google.com/specimen/Roboto+Mono?query=roboto+mono, and then i configured it in my vs code’s settings, and instead of that im getting
this font

>Solution :

Firstly install your font and Try like that:

  "editor.fontFamily": "'Roboto Mono', monospace",

Remember to restart VSCode!
