My Question or Issue

I'm using the AuthenticationRequest and AuthenticationClient to connect a Spotify account to my app. After testing a few times with installing the app, logging in through the Login Activity, deleting the app, and repeating, the log in screen started turning out blank. No matter what I do, now, I can't get the login screen back.

I've tried using different devises, wiping the device and reinstalling, restarting my IDE, and using different OS versions.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    Objects.requireNonNull(getSupportActionBar()).hide();
    setContentView(R.layout.activity_splash);

    authenticateSpotify();

    sharedPreferences = this.getSharedPreferences("SPOTIFY", 0);
    queue = Volley.newRequestQueue(this);
}

private void authenticateSpotify() {
    AuthenticationRequest.Builder builder = new AuthenticationRequest.Builder(CLIENT_ID, AuthenticationResponse.Type.TOKEN, REDIRECT_URI);
    builder.setScopes(new String[]{SCOPES});
    AuthenticationRequest request = builder.build();
    AuthenticationClient.openLoginActivity(this, REQUEST_CODE, request);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (requestCode == REQUEST_CODE) {
        AuthenticationResponse response = AuthenticationClient.getResponse(resultCode, intent);

        switch (response.getType()) {
            case TOKEN:
                editor = getSharedPreferences("SPOTIFY", 0).edit();
                editor.putString("token", response.getAccessToken());
                editor.apply();
                waitForUserInfo();
                break;

            case ERROR:
            default:
                break;
        }
    }
}

private void waitForUserInfo() {
    UserService userService = new UserService(queue, sharedPreferences);
    userService.getUserInfo(() -> {
        User user = userService.getUser();
        editor = getSharedPreferences("SPOTIFY", 0).edit();
        editor.putString("userid", user.id);
        editor.putString("email", user.email);
        editor.putString("name", user.display_name);
        editor.commit();
        startMainActivity();
    });
}

private void startMainActivity() {
    Intent newIntent = new Intent(AuthenticateSpotify.this, MainActivity.class);
    startActivity(newIntent);
}

Hey. Im actually having the a similar issue when trying to deploy my application with Vercel. It works fine on localhost. I have already tried to add the deployed redirect url to my Spotify application but only thing i get is a white screen with the message invalid redirect uri.
