    I solve the issue.
    I did two things and it works for me.

    First thing :
    I installed some of the packages via npm , so I reinstall them using expo.

    Second (it's most likely the issue) :
    My app was consuming an API I built with node.js for auth purposes , and that API was using (nodeMailer) using gmail , and google changed some of security settings , so my nodemailer doesn't send email confirmations , so I fix that + I uninstalled cors library for security reasons .

    after that everything works just fine.

    What iOS version? There are known issues with apps crashing and not being openable in iOS 15. In iOS 15, apple removed certain directories which caused many apps to crash on certain iPhones (specifically phones w/o face ID in Geometry Dash’s case). I can’t find more details on it since the google search is bloated with other results when I search it up.
