Fix black emojis

General Help

I recently installed Zorin OS Lite and saw a problem with emojis in Discord and other programs. And I don't know how to fix it. I tried changing the fonts.conf but ended up damaging the fonts. Luckily I was able to fix it because I made a backup.

Any solution you can give me for black emojis
