I am unable to open my project in Adobe premiere Rush

Good evening. I recently started editing a short video, with .MOV footage at 60 FPS 1080P. Earlier today, the project opened just fine, but after coming back to it once I left the app, the project won't open anymore. It's happened twice today already, and I have +6GB of free storage on my iPhone 11. What is happening and how can I fix it?
