How to switch activities without animation?

Question

I read a lot of similar questions but no one solution helped me. Now, I have the next code of LauncherActivity:

class LauncherActivity : AppCompatActivity(), DIAware {
    override val di by closestDI()
    private val getAccount: GetAccountUseCase by instance()

    override fun onCreate(savedInstanceState: Bundle?) {
        installSplashScreen()

        val activityClass = if (this.getAccount() == null) {
            LoginActivity::class.java
        } else {
            MainActivity::class.java
        }

        val intent = Intent(this, activityClass)
            .addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION)
            .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK)
            .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
        startActivity(intent)
        overridePendingTransition(0,0)
        finish()

        super.onCreate(savedInstanceState)
    }
}

However, it works as long as I don't call finish(). If I call finish() animations begin to show again.

Where can the problem be? I have retried all possible combinations of these lines and flags, it doesn't work with finish().

P.S. I know that I can use styles to turn off animations but it doesn't suit for my purposes, I need a solution to achieve it programmatically.

Themes.xml

<style name="noAnimation" parent="android:Theme">
   <item name="android:windowAnimationStyle">@null</item>
</style>

AndroidManifest.xml

<activity android:name=".LauncherActivity" 
   android:theme="@style/noAnimTheme">
    </activity>
