I was messing around with KDE themes and wanted to change the font. After changing the font to one I really didn’t like I’ve been unable to open the Text&Fonts tab in system settings. Whenever I try, the System Settings app crashes immediately. How can I open the Text&Fonts tab again without it crashing? Can I just reset the fonts to the default fonts through some other way?
I get why you don’t like that font 
Not sure if this’ll help but can you check if you have a “Font” entry in the “Global” section of your `~/.config/kdeglobals`? I don’t have one in there and I’m not sure where KDE sets those but it might be worth a try.
Otherwise someone with more KDE knowledge has to chime in.
Also, out of curiosity, which font is this? Maybe this is a bug with this specific font, so it might be worth reporting if I can reproduce it.
Thank you for understanding how i feel about the font
. The font name is “Noto Color Emoji”. If I were to edit this text file would I be able to reset the fonts on my system back to default?
Another issue that has appeared is in some of the KDE desktop panels a different set of icons appears. In the Calendar panel, In the Power&Battery panel, and on the start up/ sign up screen the numbers use icons unfamiliar to me. I have photos of some examples below:
Yes, that’s pretty much it. If you remove the line that starts with “fonts” (and probably all others ending with “Font”), your font settings will work again.
I think the unfamiliar icons might be due to the smallestReadableFont setting, but I’m not too sure on that one.
Also, thanks for pointing out the font you used. I can reproduce this on my system and will see if a bug about this exists upstream.
Edit: It might be this bug as the error message looks similar. Thanks for finding this!
This worked! Thank you very much, I can happily use my Linuxified Macbook thanks to you!
