Suddenly, Most of My Fonts Aren't Being Shown Correctly

[abajan]

Hi Guys,

For some reason, just a few of the fonts in GIMP are being displayed correctly. The rest are being shown without any style (no serifs nor cursive features). So far, I've tried:

• closing and reopening GIMP
  
• shutting down the computer completely and then turning it back on (instead of just restarting it)
  
• uninstalling the version of GIMP I was using (2.10.2) and installing 2.10.6
  

None of the preceding worked. Does anyone know how to fix this?

Thanks.
