Windows10 - A font doesn't appear in IntelliJ's dialog of choosing a font

 I use Windows10 Home (version 1809 & build 17763.55)

and I installed a new font named D2Coding and formated ttf.

Github link here ( https://github.com/naver/d2codingfont )

However, it doesn't appear in font setting dialog.

Reboot computer - Restart Intellij is not working.

Another apps are OK. (notepad, visualstudio code etc)

What should I do?
