The first step is to cast to resolve the ambiguous operator. Next, rearrange your query to get rid of the two extra subqueries:

Int64 memberId = reader.GetInt64(0);
var user = Context.Guild.Users
    .Where(x => x.Id == (UInt64)memberId)
    .First();

string name = 
    user.Nickname != null 
        ? user.Nickname 
        : user.Username;

Int64 votes = reader.GetInt64(2);
GOTWVote.Add($@"{name} has received {votes} vote(s)");
