Multiple binary rejection by AppStoreConnect due to launch crash - ios

Question

The build has been rejected multiple times from AppStoreConnect with always exactly the same reason
"The app crash on launch"
I've never reproduced the error. I've executed it in every available device and iOS version without success.
In addition, the crash logs that they provided me don't provide too much information.
I've tried to request more information about the environment in which they reproduced the error without success. One time, they said that the crash was in an iPad emulator, but the app works perfectly in every iPad version

I would like some feedback from you due to I literally don't have more ideas to resolve this situation.
It would be helpful if you would know the solution of the crash having in mind the logs but if you didn't I'm also listening to your next steps suggestions.
