Crashing in iOS 17

The presence of the Last Exception Backtrace section indicates that your app crashed due to an unhandled language exception. Consider this:

Last Exception Backtrace:
0   CoreFoundation    … __exceptionPreprocess + 164
1   libobjc.A.dylib   … objc_exception_throw + 60
2   CoreFoundation    … -[NSException initWithCoder:] + 0
3   FirebaseCore      … +[FIRApp addAppToAppDictionary:] + 168
4   FirebaseCore      … +[FIRApp configureWithName:options:] + 652
5   Runner            … 0x1049e0000 + 38168
6   Runner            … 0x1049e0000 + 47628
7   Flutter           … 0x105220000 + 6176028
8   Flutter           … 0x105220000 + 277504
9   libdispatch.dylib … _dispatch_call_block_and_release + 32
…

Frame 9 is Dispatch running a block on a queue. Frames 8 through 5 aren’t symbolicated, which makes things a bit tricky. Frames 4 through 3 show that your code has called a third-party library, which has thrown this language exception.

I recommend that you symbolicate your crash report to get a better understanding of how you triggered this crash; see Adding identifiable symbol names to a crash report. After that, you should consult the support resources for your third-party tooling to see why it’s throwing that exception.
