🔧 Bug deployment application expo react native

Hello, I need help. I'm new to application deployment. I have a react native expo app.
I was able to create my iOS and Android builds. Locally my application works on my iPhone and Android tablet. But when I submit with eas the application installs fine. I arrive on my login screen, I log in with my credentials, I am redirected to another screen to enter a 6-digit code to send by email. I enter the code and I am connected. But screen appears briefly for 2 seconds and then black screens. I store the token in a secure store but when uninstalling the application it keeps it. So it's problematic. I would like to point out that this problem is only due to the build. I have this problem on my iPhone, on my Android tablet and even in an iOS simulator. I'm running out of solutions.

Thank you in advance for your help
