KWGT unable to use TTF fonts

Issues
1

Using KWGT Pro ver 3.76b422110, on a Google Pixel 9 running Android 15.

TTF fonts are completely unusable in the app, with error message “Unable to read ext:/fonts/(font name).ttf”. Clearing cache does not help. The fonts are usable, as I’ve been able to install them to my PC with zero issues.
If it matters, I downloaded my fonts from FontStruct.

Are they in the Kustom/fonts folder?

3

Yes they are. In the font picker, they appear to be loading endlessly.

4

Could it be that they, for some reason, also need the .json file?

5

None of the fonts I downloaded came with a .json file, so I don’t think that’s the case.
