Rush App Crashes when using Arabic letters

Hi 

Im trying to use title graphics on a new project on media that I imported from my camera roll. 

As soon as I try to type in Arabic letter the whole app crashes. 

I have tried starting new projects, deleted and reinstalled the app, restarted my phone (IphoneX) and the same issue persists. 

kindly advise how this issue can be solved and if Rush does support Arabic. Is it possible to add such feature?
