Excuse me, what is "pr"?

Pull request, also do you have any documentation for the supported versions and api changes?

I don't have documentation.
I tried to get information about the user using VkClient in the same way as I received information using GoogleClient. But there was an exception.
Then I decided to make requests to the api myself:

    UriBuilder accessUriBuilder = new UriBuilder("https://oauth.vk.com/access_token");
    NameValueCollection accessQueries = HttpUtility.ParseQueryString(accessUriBuilder.Query);
    accessQueries["client_id"] = provider.ClientId;
    accessQueries["client_secret"] = provider.SecretKey;
    accessQueries["redirect_uri"] = redirect.ToString();
    accessQueries["grant_type"] = "authorization_code";
    accessQueries["code"] = code;
    accessUriBuilder.Query = accessQueries.ToString();

    HttpClient httpClient = new HttpClient();
    var accessResponseValue = await httpClient
        .GetStringAsync(accessUriBuilder.Uri.ToString())
        .ConfigureAwait(false);

    var accessResponse = JObject.Parse(accessResponseValue);
    string access_token = accessResponse.GetValue("access_token").Value<string>();
    string user_id = accessResponse.GetValue("user_id").Value<string>();
    string email = accessResponse.GetValue("email").Value<string>();
    
    UriBuilder userInfoUriBuilder = new UriBuilder("https://api.vk.com/method/users.get");
    NameValueCollection userInfoQueries = HttpUtility.ParseQueryString(userInfoUriBuilder.Query);
    userInfoQueries["v"] = "5.74";
    userInfoQueries["access_token"] = access_token;
    userInfoQueries["user_ids"] = user_id;
    userInfoQueries["fields"] = "first_name,last_name,has_photo,photo_max_orig,sex,bdate,phone";
    userInfoUriBuilder.Query = userInfoQueries.ToString();
    
    var userInfoResponseValue = await httpClient
        .GetStringAsync(userInfoUriBuilder.Uri.ToString())
        .ConfigureAwait(false);
    var userInfoResponse = JObject.Parse(userInfoResponseValue);

As a result, I received an error message:
Invalid request: versions below 5.81 are deprecated. Version param should be passed as "v". "version" param is invalid and not supported. For more information go to https://vk.com/dev/constant_version_updates

Fixed 5.74 to 5.81 and it worked! (5.131 is actual)

Thanks for that, if you want to submit a pull request to change the version that would be greatly appreciated.
