Hi ​@hamid jimmy, Thanks for reaching out about this.
 

Is this problem happening inside a Figma file (like when you're picking a font), or is it something going on with your computer itself?

If it's happening in Figma, shearing us a video or screenshot of your whole Figma screen would really help us understand what's going on!

Thanks!

hi

The font is installed on the system. Sometimes it recognizes the font...sometimes it says unknown. I also installed the font installer but it didn't work.
