App crashing suddenly on launch - iPhone enterprise version

I have enterprise version installed on few of the devices.
On one of the device app is crashing immediate after the launch button click every time.
It is working on other device without crash. Can any one help me on the issue that why it is crashing ?
**edit:
We seems it certificate expiration issue. But if certificate is expired then it also should not work when I install it in new device.
Here are few steps will help you to find / detect / resolve your issue :
If its live version which you are testing than check out crash logs.
To check crash logs open Xcode -> window -> Organiser -> Select your app -> Crashes -> Select current version. You will find the crash
open it in Xcode it will help you to find the line which generating
crash
If its not live app than try to debug app on same device using debug ad hoc provisioning
Another way is you can also use crashlytics tool into your app. It will give you detailed information of the crash along with the
possible code which encouraging the crash
Possible reasons for crash :
Architecture support. Might be crash issue generated only on base 64 devices than check out your app is base 64 supported or not
Use of Depreciated methods can also cause the crash
iOS Compatibility issue can also be a reason of crash
Most important reason is if your app trying to access privacy information without permission alert than also it will get crashed at
very beginning of app launch
Hope it will help you.
We figured out this but posting bit late.
Few data systems and validation not matched in case of the Date Time system used. Date Time formats are different according to user and devices. Few systems have date formate as a month in the first 3 characters longer than the year(e.g. 1 Aug 2020). (from the same region devices, the date time format could be different). so this validation is very critical and needs to consider and all test cases. This was the issue we were facing as in the start we were opening the calendar and fetching the events accordingly.
Also displaying data on threads and managing threads are also more important in this kind of case. Memory leaks and appropriate GCD usage may also lead to this situation.

Accessing data from core data when in location background mode

I have a app that get launched in the background mode by location region service , I would like to then display a local notification but I need to access core-data to get info for the notification and to query weather it should show the notification. every thing works but the query wont return any data when in the background , If it is not possible to access core-data at that time is there any other way I can store my data so I can read it while running in the background.
I did get this sort of working I think it is more of a issue with xcode 4.2 which is giving me issues I could access the core data file from the background mode only if I run the app from xcode then after I quit running I must open the app on the phone or simulator by clicking the app icon not the run button in xcode then close the app then the next time a run the app on the phone or sim by clicking the app icon not the run button in xcode then the application will access the core-data database. but local notification now wont work on the simulator unless I run form xcode which will then stop core-data access. I guess Im stuck with not being able to build this app till xcode 4.2 is at standard of xcode 3 where I could just get things to work.
Thanks for the comments I think Ive sorted it out , I did not have icloud on my iphone as its older one and I've been testing on simulator and thats is why Ive had this issue so if any one else has this problem the way to fix it is to start and stop your app in the simulator first as when you stop the app by clicking stop in xcode after running it kill the app the wrong way here is the log "9/02/12 12:46:52 PM Application '*App Name**' exited abnormally with signal 9: Killed SpringBoard[5273]" which then stops the app from accessing core data while in background , Ill send apple a bug report but I dont know if its something they want to fix . PS grate Site helpful thanks to anyone who answers Questions :)
