encountered an error in a game I’ve been working on for a long time, and unfortunately the solutions I searched on “Google” didn’t work or I couldn’t manage it.
about the problem;
The game somehow cannot connect to the “android games platform”. The interesting thing is that if I build the game in development mode, I do not experience any problems, it works perfectly fine. but if I configure it in release mode the game will run "PlayGamesPlatform.Activate();" It gets stuck in its code and does not continue.
So how do I know this: When I replace this code, the previous codes work.

As for detailed information:

The Unity version I use is: 2022.3.5f1.

The error I get from android logcat:

• AndroidJavaException: java.lang.ClassNotFoundException: com.google.android.gms.games.PlayGames,
• Unity java.lang.ClassNotFoundException: com.google.android.gms.games.PlayGames,
• Error Unity at java.lang.Class.classForName(Native Method).

etc…

Part of the code I wrote:

public void Start()
    {
       StartCoroutine(FirstDoorsOpening()); // this is the game opening      
    }
    IEnumerator FirstDoorsOpening()
    {
        yield return new WaitForSeconds(0.8f);
        PlayGamesPlatform.Activate(); // This was normally at the start
        yield return new WaitForSeconds(0.4f);
        SignIn();
    }
    public void SignIn()
    {   
         PlayGamesPlatform.Instance.Authenticate(ProcessAuthentication);
    }
    internal void ProcessAuthentication(SignInStatus status)
    {
        if (status == SignInStatus.Success)
        {
            AuthenticationSuccess();
       }
        else
        {          
        detailsText_Negative.text = "SIGN IN FAILED  PLEASE CHECK YOUR CONNECTION";
        }
    }
    void AuthenticationSuccess()
    {
        StartCoroutine(GotoFirstScene());
    }
