You can't use the same collection navigation property to represent the requests where the user is the sender and the requests where the user is the target.

You also can't use the RequestId property as the foreign key to the users table - you're not creating a one-to-one relationship, so the request ID and the user ID will be different.
C#
public class User
{
    ...
    public List<Request> SentRequests { get; set; }
    public List<Request> ReceivedRequests { get; set; }
    ...
}

...

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Request>()
                .HasOne(m => m.SenderUserRef)
                .WithMany(t => t.SentRequests)
                .OnDelete(DeleteBehavior.Restrict);

    modelBuilder.Entity<Request>()
                .HasOne(m => m.TargetUserRef)
                .WithMany(t => t.ReceivedRequests)
                .OnDelete(DeleteBehavior.Restrict);
}
