EXC_BAD_ACCESS on IOS with codepush restart

[Sangkwun]

dependencies:

• "react-native-mmkv": "^2.12.1"
• "react-native-code-push": "8.1.0"
• "react-native-quick-crypto": "^0.6.1"

OS: iOS only

Generally, using MMKV and CodePush together does not cause issues. However, it seems that after performing encryption/decryption using react-native-quick-crypto, problems arise during the CodePush update process due to the PropNameIDCache::invalidate step in MMKV.

I encountered an error while using the react-native-mmkv library during the CodePush update process. The error message I received is as follows

An easier approach would be to not use react-native-quick-crypto, but it seems like modifying MMKV could also be a good solution.
