Mismatch between JavaScript code version and Worklets Babel plugin version

Sometimes an error occurs when updating React Native Reanimated, and it asks to install worklets along with it. Then, when you run the app, an error appears saying:"Mismatch between JavaScript code version and Worklets Babel plugin version."

This error usually appears when you repeatedly update it, even after installing the compatible version, but the error still remains and keeps showing every time you run the app again.

So first, you need to check whether your React Native and Reanimated versions actually match or not. Their compatibility looks something like this:
