System.PlatformNotSupportedException: 'Secure binary serialization is not supported on this platform

Please I need help for the below error I am getting. Whenever I query with the value that exists in the servicecontainer, it works fine. When the value does not exists, the below error surfaces:

code line that gives error:

BusinessPartner bp = currentServiceContainer.BusinessPartners.Where(
                    c=> c.cn==cn).SingleOrDefault();

I am using .Net core 2.2

Thanks
