🐛 iOS Crash (EXC_BAD_ACCESS) in Realm JSI when reloading app (React Native 0.77.3 + Hermes + Realm 20.1.0)

### How frequently does the bug occur? Sometimes ### Description We are experiencing a native crash on iOS when the React Native app reloads (using RNRestart / JS bundle reload). The crash occurs inside Realm JSI during runtime reinitialization and results in: EXC_BAD_ACCESS (KERN_INVALID_ADDRESS) Crashed: com.facebook.react.JavaScript This appears to happen during JS bundle reload when Realm attempts to access a destroyed or invalid JSI runtime. 💥 Crash Details Crash thread: Crashed: com.facebook.react.JavaScript EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000033a40 Top stack frames: realm::js::(anonymous namespace)::ContainerResizer<...>::~ContainerResizer() realm::js::JSI::(anonymous namespace)::Realm_get_shared_realm(...) facebook::react::JSIExecutor::loadBundle It crashes during JS bundle loading after restart. 🔎 Additional Notes This only happens when triggering runtime reload. Does NOT happen on cold start. Appears related to JSI runtime being destroyed and recreated. We suspect Realm is holding a reference to an invalidated Hermes runtime during reload. Faced multiple crashes : realm::js::JSI::(anonymous namespace)::RealmCoordinator_clear_all_caches(facebook::jsi::Runtime&, facebook::jsi::Value const&, facebook::jsi::Value const*, unsigned long)
