Android gets Bigint error

When I use rKey on react native project. IOS works fine but Android gets Bigint error

```
Require cycles are allowed, but can result in uninitialized values. Consider refactoring to remove the need for a cycle.
ERROR ReferenceError: Can't find variable: BigInt
ERROR Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication). A frequent cause of the error is that the application entry file path is incorrect.
This can also happen when the JS bundle is corrupt or there is an early initialization error when loading React Native

```

```

How to fix it

Start by reproducing the Android failure with the listed React Native 0.64.4 and TKey dependency versions, comparing it with the working iOS behavior. Trace the early initialization error associated with BigInt and verify that the Android app launches without the BigInt or AppRegistry errors.
