Dagger Hilt impossible to inject kotlin data class

I am trying to use Dagger Hilt in order to inject a data class in my code. My goal is to be able to have a single data structure that I can inject everywhere.

I have defined a data class as below:

data class UserInfo @Inject constructor(
    var lastname: String,
    var firstname: String,
    var email: String)

I have tried to use this data class in my MainActivity as below:

@AndroidEntryPoint
class MainActivity : AppCompatActivity() {

    @Inject
    lateinit var userInfo: UserInfo

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        initValue()

    }
    
    fun initValue() {
        userInfo.email = "ste@gmail.com"

    }

I keep getting error like

public abstract static class SingletonC implements DriverApplication

I tried to add Singleton but it's also generating the issue.

I just try to have one single data class to store information and use this information everywhere in my code.

Any idea ?
