Why doesn't CSVHelper read fields from file?

Question

ASP.NET

I'm having a problem, csvhelper doesn't see any of the fields in my .csv file (there are many)

static OFSStoresDB ReadFile(string filename)
        {
            OFSStoresDB db = new OFSStoresDB();
            StreamReader reader = new StreamReader(filename);
            CsvReader csv = new CsvReader(reader);
            csv.Read();
            csv.ReadHeader();
            csv.Configuration.HasHeaderRecord = true;
            csv.Configuration.BadDataFound = null;
            // Log missing field.
            csv.Configuration.MissingFieldFound = (headerNames, index, context) =>
            {
                Console.WriteLine($"Field with names ['{string.Join("', '", headerNames)}'] at index '{index}' was not found. ");
            };
            while (csv.Read())
                {
                    #region Read raw data

                    var timestampConverter = new TimestampConverter();

                    DateTime reportExtractedAt = csv.GetField<DateTime>("Report_Extracted_At", timestampConverter);

                    // Source Store
                    string srcStoreId = csv.GetField("Src_Store_Id");
                    string srcStoreName = csv.GetField("Src_Store_Name");

....
And already at the first reading of the first field, an error occurs

System.ArgumentNullException: 'Value cannot be null. Parameter name: value'

And in the console writes

Field with names ['Report_Extracted_At'] at index '0' was not found.

What could be the problem, please advise.

(on a comment to the question) ... or with a separator "by default" ("," or ";". in the Russian locale it's just ";") .. dig in the direction of setting the locale for the length of the sieswi-reader. a simple example here https://progtask.ru/csv-c-sharp/
