Premiere Rush Keeps Crashing! iPhone 13

I have been using Premiere Rush since June. And all along June and July it was working just fine and I loved it. However, since the last 3-4 days (August 1st till now), it just keeps crashing while I'm working on it on my iPhone 13. It happened once then I started again from scratch, happened again and again. 3 times already! And whenever I try to work on it again, it just keeps crashing, the same happens when I duplicate it and work on the duplicated file, it crashes too when I try to export it!!

I visited this page, saw Mr.Monahan's suggestions and applied them all, updated the Premiere Rush itself, and my iPhone (iOS 17.6), signed out and then in, restarting my phone, deleting the app and reinstalling it, calling the customer service who were nice but didn't give any effective solution! And NOTHING WORKED OUT!

Please help me out because I'm losing my mind!
