Hello mashiwomurakami,

 Sorry Rush is not exporting successfully for you. I'd love to try to figure this one out. If you're willing to share some more details about your project, that would be very helpful.

1. Were all of the clips in your project recorded on your phone? 1080 or 4? 
2. Do you have other effects applied? Color? Speed? Transitions? Titles?
3. Can you create a screen recording of the crash? That way I can see your project and see when the app is crashing? Here's how https://support.apple.com/en-us/HT207935
4. Can you please share the logs from your device. Here's how 

• Launch Rush > Tap on the App Settings (top left of screen) 
• Go to Preferences > Share Logs

Here are a few things you can try that can sometimes improve iPhone performance  

Perform a hard reset on the iPhone

1. Press and release the Volume Up button
2. Press and release the Volume Down button
3. Press and hold the Power button, hold until you see the  Apple logo appear on screen

• Close background apps

A workaround, for now, could be syncing your project to the desktop and exporting from there. 

Sorry again that the exports aren't working. Hopefully, the information above will help figure out what the cause is. 

Thanks, 

Peter
