Crash on open from alert

[renanpupin]

The following code causes app crash when is opened twice.

Steps to reproduce:

• Click in a button that executes this alert.
• Click the YES button.
• The intercom message composer is opened.
• Close the message composer.
• Click the in button to open it again
• CRASH

Alert.alert( 'Open intercom', 'Do you want to open it?', [ { text: 'YES', onPress: () => { Intercom.displayMessageComposer(); } } ], );

I can confirm that it is happening triggering an alert after open messenger.

I've also encountered this error. Showing an alert at a later point (after the messenger has been opened) will crash the app with the following message:
