Bug Site favicon / admin avatar showing for all users instead of social profile avatars

I am facing an issue with user avatars on my WordPress site.

Currently, the site favicon or admin avatar is showing as the avatar for all users, even when users log in via social login (Google or X).

Expected behavior

• If a user logs in using Google, their Google profile photo should appear.

• If a user logs in using X, their X profile photo should appear.

• Only users without a profile image should fall back to a default avatar.

Actual behavior

• All users are getting the same avatar, which appears to be the site favicon or admin email avatar, regardless of how they log in.

Question
How can I configure WordPress so that:

• Social login users display their own social profile image, and

• WordPress does not override avatars with the site favicon or admin avatar?

I have attached the settings screenshot for reference.

Any guidance on the correct settings, filters, or plugins to fix this would be appreciated.
