[Compiler Bug]: TypeError: isUndefined is not a function (it is undefined)#33052

### What kind of issue is this? - [x] React Compiler core (the JS output is incorrect, or your app works incorrectly after optimization) - [ ] babel-plugin-react-compiler (build issue installing or using the Babel plugin) - [ ] eslint-plugin-react-compiler (build issue installing or using the eslint plugin) - [ ] react-compiler-healthcheck (build issue installing or using the healthcheck script) ### Link to repro https://github.com/Robert27/react-compiler-repro ### Repro steps This bug happens in my Expo app and only with the [calendar lib](https://github.com/howljs/react-native-calendar-kit). The repro repo uses the react compiler version expo recommends, but it also happens with React 19.1 with the latest React compiler alpha version. 1. Navigate to `Calendar` tab. 2. Error: `TypeError: isUndefined is not a function (it is undefined)` The only workaround is to completely disable the compiler. Using `'use no memo'` or disabling the file in the babel config does not work. ### How often does this bug happen? Every time ### What version of React are you using? 19.0 ### What version of React Compiler are you using? 19.0.0-beta-af1b7da-20250417
