Я искал сообщение об ошибке в Google, и оно сообщило мне об этом на Github: https://github.com/takahirom/DownloadableCalligraphy/pull/4/commits/3707383200749b385cc77adb2bb1aaf447420d62, но я не мог связать это!

Кажется, что это известная проблема для библиотеки каллиграфии: https://github.com/chrisjenx/Calligraphy/issues/475

Не могли бы вы попытаться перейти на Caliligraphy 3: https://github.com/InflationX/Calligraphy?
