Exception when calling PlayGamesPlatform.Instance.LoadUsers

[Manoloman]

The bug:
Calling the method PlayGamesPlatform.Instance.LoadUsers results in a null pointer exception due to some kind of internal problem with the setAvatar method.

To Reproduce:
Steps to reproduce the behavior:

1. Complete the platform sign-in action.
2. Call PlayGamesPlatform.Instance.LoadScores to get a list of IScores containing the users userId.
3. Call PlayGamesPlatform.Instance.LoadUsers with the array of userIds to retrieve username and avatar
   *Same error calling LoadUsers with the localplayer userId.

Expected behavior:
An array of IUserProfile that would include the usernames and avatars used in the learderboards by these users should be obtained.

Observed behavior:
The call throws an exception with this message:

Versions:

• Unity version: 2021.3.45f1 (same issue in 2021.3.15f1)
• Google Play Games Plugin for Unity version: 2.0.0

Additional context:
I'm able to send score to the leaderboards, achievements etc. so the signin is correct. I saw some users creating custom leaderboards retrieving the information using this same LoadUsers method.
I tried applying LoadUsers in the own local user userid too with the same result.
