🎯 Subject of the issue
The patched Iosevka Mono fonts are more or less broken
Some Iosevka Mono fonts can not be opened at all (or it takes more than some minutes), while most other open with error messages of this kind:
patched-fonts/Iosevka/Thin-Italic/complete/Iosevka Thin Italic Nerd Font Complete Mono.ttf

I believe fontforge tries to fix the fonts that do not open for extended times like this:

I guess the problem is the ligature removal with the src/unpatched-fonts/Iosevka/config.json.
