  I have reproduced the problem and it occurs because of SecureStorage. We have used in exactly same way with the MAUI documentation but it doesn't respond at runtime in release mod only on Android. It seems it's related to MAUI implementation.

  You can use Preferences API or use a simple Sqlite to keep data in the DefaultStorage implementation as a workaround. We aware the problem but we don't have a solution for android yet

  I've done some experiments that I hope will help.

  1. Create a Hello World solution for maui
  2. Trigger SecureStorage by clicking a button

  This is not working code

  private void OnCounterClicked(object sender, EventArgs e)
  {
      count++;
  
      if (count == 1)
          CounterBtn.Text = $"Clicked {count} time";
      else
          CounterBtn.Text = $"Clicked {count} times";
  
      SecureStorage.Default.SetAsync("__access_token", CounterBtn.Text).GetAwaiter();
  
      var values = SecureStorage.Default.GetAsync("__access_token").GetAwaiter().GetResult()!;
  
      SemanticScreenReader.Announce(values);
  }
  

  This is working code

  private async void OnCounterClicked(object sender, EventArgs e)
  {
      count++;
  
      if (count == 1)
          CounterBtn.Text = $"Clicked {count} time";
      else
          CounterBtn.Text = $"Clicked {count} times";
  
      await SecureStorage.Default.SetAsync("__access_token", CounterBtn.Text);
  
      var values = await SecureStorage.Default.GetAsync("__access_token");
  
      SemanticScreenReader.Announce(values);
  }
  

  I think the relationship between void OnCounterClicked and async void OnCounterClicked is async

  I think CurrentPrincipalAccessorBase increase async can be solved, like this

  protected abstract Task<ClaimsPrincipal> GetClaimsPrincipal();
