'ExponentImagePicker.launchCameraAsync' has been rejected

Question

On a specific device (Samsung Galaxy S9 with Android 9), when I try to open the camera through ExponentImagePicker, I get the following error:

Error: Call to function 'ExponentImagePicker.launchCameraAsync' has been rejected.
Caused by: kotlin.UninitializedPropertyAccessException: lateinit property cameraLauncher has not been initialized

On an Android 9 emulator it works, and also for newer API version emulators. This was working previously, but seems to have stopped working after updating react native and other libraries.

Anything I can do about it?

Code:

import * as ImagePicker from 'expo-image-picker';

const MediaSelector: React.FC<Props> = (props) => {
    const open = async () => {
        const permissions = await ImagePicker.requestCameraPermissionsAsync();
        if (!permissions.granted) return Alert.alert("permission denied!"))
        
        const config: ImagePicker.ImagePickerOptions = {
            mediaTypes: ImagePicker.MediaTypeOptions.Images,
            allowsEditing: true,
            allowsMultipleSelection: false,
            exif: false,
            aspect: [1, 1],
        }
        try {
            const result = await ImagePicker.launchCameraAsync(config);
        } catch (error) {
            console.log(error)
            Alert.alert("error!")
            return
        }
    }
    
    return <Pressable style={styles.container} onPress={open}>
        <ImageView img={props.image}/>
    </Pressable/>
}

versions:

"react": "18.0.0",
"expo-image-picker": "~13.3.1",
"react-native": "0.69.6",

I had the same issue, and for some reason using getCameraPermissionsAsync() fixed the issue - whereas requestCameraPermissionsAsync() on its own would cause launchCameraAsync() to be rejected on Android devices.

See the following:

let permissionResult = await ImagePicker.getCameraPermissionsAsync();
        if(permissionResult.status !== 'granted') {
            permissionResult = await ImagePicker.requestCameraPermissionsAsync();
        }
        if(permissionResult.status !== 'granted') {
            alert("You must turn on camera permissions to record a video.");
        }
        else {
            let result = await ImagePicker.launchCameraAsync({
                mediaTypes: ImagePicker.MediaTypeOptions.Videos,
                allowsEditing: true,
                aspect: [3, 4],
            });
