Why does the app crash after deleting TTF fonts?

In AndroidBuilder project I deleted TTF font file in my assets folder. After that when running App it is crashing directly and not starting.

This sometimes happens due to a glitch. Even if you delete the TTF file from assets, the project may still try to reference it. You’ll need to manually check and remove it from all components where the FontTypeface property is set to that deleted font. After clearing those references, your app should run without crashing.
