Fonts in Regular and Bold format appearing as an incorrect font

[Alice26702168hnmq]

My fonts were working fine yesterday, I have re installed the font and Premiere but I am still having this issue. 

The font when selected to be regular bold appears as a different font - looks like Helevetica. As light or semi bold it works, but bold does not.

Is this happening to all fonts or just a particular font?

If a particular font, where is it from, and how did you install it?

If all fonts, try resetting the preferences:

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver).

If that doesn't work, try creating a new project and import the old one into it.ut.
