[IOS] ChromeSafariBrowser.open fails with EXC_BAD_ACCESS (SIGSEGV) in simulator

[ne3Vubeki]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When trying to open ChromeSafariBrowser.open only in the simulator with IOS 18, the browser opens and the browser opens and freezes.

After which the simulator exits with a MacOS error trace. For the simulator with IOS 17.5, this does not happen. There are no problems on real devices.

Expected Behavior

Will work in simulator with IOS 18

Steps with code example to reproduce

Steps with code example to reproduce

    final isAvailable = await ChromeSafariBrowser.isAvailable();
    if (isAvailable) {
      this.browser = ChromeSafariBrowser();
      try {
      this.browser!.open(
            url: WebUri(url),
            settings: ChromeSafariBrowserSettings(
              shareState: CustomTabsShareState.SHARE_STATE_OFF,
              isSingleInstance: false,
              isTrustedWebActivity: false,
              keepAliveEnabled: true,
              dismissButtonStyle: DismissButtonStyle.CLOSE,
              presentationStyle: ModalPresentationStyle.OVER_FULL_SCREEN,
            ),
          );
      } catch(e) {
        Error.errorPrint(e);
      }
    }
