Auto friends head into a question mark.

There are several reasons why the car friend's head becomes a question mark:

1, network problem: the network connection is unstable, and the Steam client cannot load the avatar correctly.

2.Steam server problem: The steam server is out of order or maintained, which causes the avatar not to be displayed normally.

3. Friend Settings: Some friends will be set to not allow their avatars to be disclosed, in which case they will not be able to see their avatars.
