[IconButton] Error Check the render method of `ForwardRef`. in 5.14.5

### Current behaviour
Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports

Check the render method of `ForwardRef`.

### Expected behaviour
No errors

### How to reproduce?
install 5.14.5, add this component anywhere. it will crash in runtime.

```react
null} />
```

### Preview

### What have you tried so far?
reverting back to 5.14.4 solves an issue.

### Your Environment

| software | version
| --------------------- | -------
| ios | V
| android | ?
| react-native | 0.79.4
| react-native-paper | 5.14.5
| node | 24.2.0
| npm or yarn | npm
| expo sdk | 53.0.9

Start by reproducing the crash with react-native-paper 5.14.5 and the IconButton example under the listed React Native and Expo versions. Compare the behavior with 5.14.4 and trace the IconButton render path to identify the regression; done means the component renders without the reported runtime error.
