iOS 18 Bug Causes Repeated Messages App Crashes and Data Loss

Replying to a shared Apple Watch face in a thread can crash the Messages app, affecting both users and leading to lost chat history.

The bug is triggered when an Apple Watch face is shared and replied to within a thread on iOS 18.
Both the sender and recipient of the watch face experience repeated crashes of the Messages app.
The only current solution involves deleting the entire conversation, resulting in the loss of all messages and attachments.
Users are advised to avoid sharing or replying to watch faces until Apple releases a fix.
Apple is expected to address this issue in an upcoming iOS 18 point update.
