Did you ever get a resolution or more info for this? I'm facing the same issue and have also only seen it on iOS 16 so far. I've seen several memory related error messages accompanying the crashes: malloc: Incorrect checksum for freed object 0x1271ce1c8: probably modified after being freed. Corrupt value: 0x3f58fec800000000 malloc: tiny_free_list_remove_ptr: Internal invariant broken (prev ptr of next): ptr=0x1574c3f10, next_prev=0x30000022c447191 malloc: Corruption at 0x108dd3c30: unexpected msizes 0/43 malloc: tiny_free_list_remove_ptr: Internal invariant broken (prev ptr of next): ptr=0x14c891e90, next_prev=0x0 malloc: Corruption of free object 0x14d369fc0: msizes 14424/0 disagree
