@DTS Engineer Is there anything we can do to prevent those crashes? It seems that this thread died, but those crashes still happen in all 3 our apps. Thank you.

Hey, did you figure out your issue? I'm facing IN CLIENT OF LIBMALLOC: memory corruption of free block I asked about it in apple dev forum some time ago, but haven't heard back. Standard memory debugging tools mentioned by Quinn were not helpful. It seems the iOS 18.4 changed malloc implementations.
