What happened?

After following the official documentation and video to set up the environment for using Kakao social login, I tested it on a physical device. When the social login event is triggered, the Kakao app launches as expected, but the login UI briefly appears and then immediately disappears.

Just to be sure, I checked the native app key and confirmed it is correctly entered. I also logged the value from the .env file in the terminal and verified that it is being printed correctly.
