Ue5 iOS game crashes on second playthrough.

My ue5 iOS game is on TestFlight and crashes on the second play through. By second play through I mean after I reopen the app it doesn’t allow me to open any levels other than the tutorial level. The problem is fixed after I reinstall the game. Is this due to memory being used up insanely fast and if so how do I fix it. Feel free to ask me questions about my project.

Mainly I just have a lot of questions that I’m struggling to find the answers to regarding the right settings for mobile.
