YallaChat iOS App Keeps Crashing Automatically Upon Opening

I am using the YallaChat iOS application and it keeps closing automatically while I am using it. This problem occurs every time I open the app and makes it impossible for me to use the service properly. I am very upset and frustrated because I cannot use the app at all. I kindly request that this bug in the iOS version be urgently checked and fixed as soon as possible with an update so that I can use the application in a stable way again. Please solve this problem without further delay.
