Yes, it appears that the error is caused by a problem when deserializing a JSON object that is returned by a web service called VirusTotal. Specifically, the code indicates that an exception occurred when creating the "YearMonthDayConverter" object of the "DateTimeParsers" class in the VirusTotalNet.Internal library. This could be caused by a problem with the system's culture configuration, as suggested by the "CultureNotFoundException" error.

It is possible that there is an incorrect or incomplete configuration of the development environment, such as a language setting or cultural configuration not supported by the system. It could also be a problem with the VirusTotalNet.Internal library itself. A possible solution would be to check the system's cultural configuration or look for an updated version of the library that would solve the problem.

I thought I only needed the invariant culture to parse datetimes. Turned out to be wrong.

Should no longer be an issue in the 1.8.0 release.
