[Bug]: CarPlay Simulator crashes on iOS versions > 26.3

Is there an existing issue for this?

• I have searched the existing issues

Description of the bug

The CarPlay example works on the iOS 18 simulator, but on iOS 26.4.1 and above the CarPlay crashes immediately when the CarPlay scene launches. However the app process does not crash. Apple’s CarPlayTemplateUIHost crashes with doesNotRecognizeSelector in CPSMapTemplateViewController _updateShareButtonVisibility / _configureNavigationBarShareButton.

I reduced the setup to a bare minimum CPMapTemplate() with no Google map content, and it still crashes, which suggests an Apple CarPlay Simulator regression rather than an issue in the React Native integration.

Needs further investigation.

I did some additional testing around this issue and based on the results this does not appear to be specific to the React Native Navigation SDK.

To isolate the problem, we tested the following:

1. Created a completely new isolated native iOS CarPlay app with no React Native or Google Maps dependencies.
2. Tested Apple’s official CarPlay navigation app example:
   https://developer.apple.com/documentation/CarPlay/integrating-carplay-with-your-navigation-app

In both cases the same crash still occurs when using the iOS versions > 26.3.

Based on this the issue is very likely caused by iOS/CarPlay simulator, Xcode, or Apple’s tooling rather than by this plugin.

So far we have not found a workaround for the crash. The only reliable way we have found to avoid the issue for now is to keep using iOS 26.3 or earlier where the crash does not occur.
