iOS Crash: Occasional crashes

[houhongcao]

Submission checklist

• I have confirmed the issue is present in the latest version of @rive-app/react-native
• I have searched the documentation and forums and could not find an answer
• I have searched existing issues and this is not a duplicate

Description

My preliminary analysis, These do not appear to be three separate issues, but rather the same underlying problem manifesting in different places. They all seem to be concentrated around Rive + React Native Nitro + DataBinding/ViewModel lifecycle and thread-safety behavior. Based on the crash stacks, we suspect the issue may be caused by internal Rive Runtime objects being accessed after deallocation, released multiple times, or accessed concurrently across threads.

The crash points vary (Artboard, ViewModelInstance, DataBinding, dictionary mutations, etc.), but the call stacks consistently point back to the same Rive Runtime area.
