Symbolicate app review crash log

I have a .NET8 iOS app that works fine in local testing but is consistently crashing in app review. I have the original dsym and the crash log, but symbolicating the log only partially reveals the details.

I've tried using atos to look up individual hex addresses, but this is still as good as I can get. It is much too vague for me to pinpoint the problem, so I'm stuck. Any suggestions on how to resolve this?
