we are also seeing this issue on the latest React native version. 

"react-native": "0.72.4",or     "react-native": "0.71.4",

"@intercom/intercom-react-native": "^5.2.0",

maybe i’m doing some wrong thing, but when login user I got the details about it and do such a code: 

useEffect(() => {
    if (user) {
      Intercom.setUserHash(user?.uuid).then(() => {
        Intercom.loginUserWithUserAttributes({
          email: user?.email,
          userId: user?.uuid,
          languageOverride: 'en',
          signedUpAt: Date.now(),
          unsubscribedFromEmails: false,
        });
      });
    }
  }, [user]);

also tried without setUserHash and only with email and uuid. 

this is the stack: 
 

Exception '-[NSNull code]: unrecognized selector sent to instance 0x1bbb347d8' was thrown while invoking loginUserWithUserAttributes on target IntercomModule with params (
        {
        email = "daria.xxxxx@buildbook.co";
        languageOverride = en;
        signedUpAt = 1693481234436;
        unsubscribedFromEmails = 0;
        userId = "xxxx-xxxx-xxxxc4a";
    },
    688,

)
