index.js file missing from node_modules\@react-native-community\masked-view after installation.

I am getting this below error while building react-native app. @react-native-community/masked-view and @react-navigation\stack are up to date but not sure why this package is not being resolved while building.

```
error: Error: While trying to resolve module `@react-native-community/masked-view` from file `C:\..\..\node_
modules\@react-navigation\stack\src\views\MaskedViewNative.tsx`, the package `C:\..\..\node_modules\@react-n
ative-community\masked-view\package.json` was successfully found. However, this package itself specifies a `main` module
field that could not be resolved (`C:\..\..\node_modules\@react-native-community\masked-view\index.js`. Indeed, none of these files exist:

**Temporary solution:**

I have tried uninstalling @react-native-community/masked-view a few times. I have tried deleting node modules folder, clearing cache using commands like npm cache clean --force, react-native start --reset-cache but nothing worked so far.

Then I realized @react-native-community/masked-view package is missing index.js file from installation.

I copied js folder and index.js file from another project for @react-native-community/masked-view and project starts building again.


I am not sure why this folder and index file is missing from the installation itself.

Any help on this issue is much appreciated.
