Keeps Crashing as long as I edit the sequence

[Yutaro sakai]

I always use premier rush in my iPhone. When I edit my video on that, it suddenly turns off and go back to my home screen of my iPhone. I didn't figure out how that happens like this is because of short storage, what I make a mistake on the process of editing or what.

please teach me how to solve it. I am in a hurry to submit my video..

Are you saying that you are both on iPhones and that you're using the same operating system?

How much free storage space is on your device?

How long is your project?
