System.Globalization.CultureNotFoundException: Culture name zm is not supported. Parameter name: name

Question

Good Day

i get this error reported in Appcentre and the device profile is the following

{
"length": 0,
"offset": 0, ,
"exception": {
"type": "System.Globalization.CultureNotFoundException",
"message": "Culture name zm is not supported.\nParameter name: name",

"appVersion": "1.81",
"carrierName": "Airtel",
"carrierCountry": "zm",

}
}

and this fails in this code

    try
    {
        I18N.Current
      .SetResourcesFolder("Locales") // Optional: The directory containing the resource files (defaults to "Locales")
      .Init(GetType().GetTypeInfo().Assembly); // assembly where locales live
        GenericMethods.DEFAULT_LOCALE = DependencyService.Get<IServiceImei>().GetDefaultLanguage();

        if (GenericMethods.USER_DATA != null)
            I18N.Current.Locale = GenericMethods.Convert_Language_to_Locale(GenericMethods.DEFAULT_LOCALE);

        string CountryCode = GenericMethods.DEFAULT_LOCALE = DependencyService.Get<IServiceImei>().GetDefaultCountry();

        Title = "About";

        RegionInfo myRI1 = new RegionInfo(CountryCode);
        string Country = myRI1.TwoLetterISORegionName.ToString();
        SelectedCountry = CountryUtils.GetCountryModelByName(Country);
        ShowPopupCommand = new Command(async _ => await ExecuteShowPopupCommand());
        CountrySelectedCommand = new Command(country => ExecuteCountrySelectedCommand(country as CountryModel));
    }
    catch(Exception ex)
    {
        Task.Run(() => Crashes.TrackError(ex));
    }

This works perfectly well with all other countries but with the following

System.Globalization.CultureNotFoundException: Culture name tz is not supported. Parameter name: name

System.Globalization.CultureNotFoundException: Culture name bj is not supported. Parameter name: name

System.ArgumentException: Region name tg is not supported. Parameter name: name

System.Globalization.CultureNotFoundException: Culture name mz is not supported. Parameter name: name

System.Globalization.CultureNotFoundException: Culture name na is not supported. Parameter name: name

Gives this error

Thanks
