Xamarin iOS build rejected by Apple EXC_BAD_ACCESS (SIGSEGV)

Question

Apple have rejected our latest build by saying its crashing, please see the log. But with Adhoc profile, it worked when in testing stage but somehow when we publish to app store, apple is saying they are not able to run this and is crashing. We've spent a day to understand what the issue could be but not sure how we read this log and fix the issue.

Here is the log from apple.

This is a actually AppStore build. Adhoc build works just fine without any issue but when we create a build for app store and submit to apple for review, they are saying its crashing. — Safeer Ahmad, Mar 11 '20 at 17:15
Symbolize the crash so you can see where in the code it is faulting (I would *assume* w/ the EXC_BAD_ACCESS it is a `null` pointer error) — SushiHangover, Mar 11 '20 at 17:28
you can make an AdHoc build in either Debug or Release, I am asking if you have actually tested with a RELEASE build — Jason, Mar 11 '20 at 18:31
Hi, We figured it out basically it was due to push notifications device id changes on iOS 13. We didn't encounter it as their devices were already registered but apple faced it as they installed the build on a new device. Now looking at https://stackoverflow.com/questions/58027344/how-to-get-device-token-in-ios-13-with-xamarin to resolve the issue. — Safeer Ahmad, Mar 12 '20 at 19:34
@SafeerAhmad Glad you found the solution . You mean the deviceToken is different with before , and need to modiy them .Right ? — Junior Jiang, Mar 13 '20 at 02:14
Yes, that's right but the above fix is not working for me. How do I "Symbolize the crash"? — Safeer Ahmad, Mar 13 '20 at 13:32
