When i set text in text buffer its just crashes

Hi! 👋 Could you please provide the full error message? If it crashes at set_text then it could be an issue in cosmic_text instead of glyphon

It crashes at set text, but i cant provide error masage because of android 💀 (idk why android logger not working)
I also dont know how i can set font. Maybe i just not set it?

Will be cool if you test it, because im on aarch64

Maybe you can fix it, and if target is android you just get fonts from system?
