Unable to customise products getting error "Unfortunately an error has occurred"

Due to a security hotfix on Windows Updates. (https://support.microsoft.com/en-gb/help/4524420/kb4524420), our application got affected and was not able to handle browser cookies efficiently. ASP.NET is now handling the SameSite entry in a different way and assigning a default value that was not expected by our application. Once the issue got detected and isolated, we were able to adjust our application settings to make it work properly.
