Hi, I'm encountering a crash when attempting to enumerate contacts using a block-based enumeration method. The crash log shows an EXC_BAD_ACCESS error. I suspect the crash may be related to a memory management issue, but I'm having trouble pinpointing the exact cause. The crash have on Crashlytics but can not reproduce. Has anyone else encountered this issue or have any suggestions for troubleshooting this type of crash? Any help would be greatly appreciated. Thank you!

From iOS 15.4.0 we have the crash below on Crashlytics but don't known how to reproduce and fix it. I hope someone can provide some insights to fix this.
