The app suddenly crashes from the initial load for some users.

[Islam1]

I have a problem with some of my apps and some of their users. The loading of the app doesn't complete until the bar is about three-quarters full. After that, the app completely exits the app sheet and redirects to the phone's background.
What is the reason for this?

For further clarification: Two of my apps work well for some users, but this problem occurs for others. One of the users experiencing this problem tested the app on a tablet and found that the problem had disappeared, but it only occurred on his phone. He has a strong internet connection and the phone's RAM, processor, and storage capabilities are good. His phone also works well with the rest of my apps.

Try using a new framework. I had similar problems on Android devices. After switching to a new framework, no problems.
