Rush still CRASHING!

Folks,

Two days ago, I had this crashing problem (Rush closes and goes back to the iPhone main screen) and updated Rush and my iPhone iOS. For 12 hours Rush appeared to be fixed, as it wasn't crashing while editing.  But now, it crashes when I try to export edited video to the phone.  I've had to download a third party editor now to get my videos done.

im on the latest iOS and Rush versions on an iPhone 13.

help!
