Adobe premiere rush is not rendering the video on my iPhone 8 with latest rush version and iOS 13?

[#1]

I have been trying again and again and again to render the video, I have tried switching video quality and frame rates but Rush app keep crashing. I have paid for the full software and I have my final uni assessment, in which I have to present my video. Is there any way, through which I can save the video on my phone. I am so worried. Please help me out.
