goBack() automatically triggers while moving from drawer to stack in nested navigator react-native

Question

I am trying to reach PatientDetails screen, For the first time after starting the app it behaves abnormally(navigating to patientdetails screen and automatically coming back to dwawer navigator), after one abnormal behaviour everything works fine, Same problem is facing in every case of navigating from drawer to stack navigator I am not getting any error in console.....

Any solution for this problem?

const MainNavigator = (props) => {
    return (
        <NavigationContainer>
            <Stack.Navigator
                screenOptions={{ headerShown: false }}
            >
                <Stack.Screen name='StackNavigator' component={StackNavigator} />
                <Stack.Screen name='DrawerNavigator' component={DrawerNavigator} />
                <Stack.Screen name='AddPatient' component={AddPatient}
                    options={{
                        headerShown: true,
                        headerTitle: "Add Patient",
                        headerTitleStyle: { color: Colors.white },
                        headerStyle: { height: constants.headerHeight, backgroundColor: Colors.splashScreen },
                        headerBackTitleVisible: false,
                        headerTintColor: Colors.white
                    }}
                />
